2 INSTALLATION REQUIREMENTS No special software installation is required. The Little Phatty Editor Librarian is a stand alone program designed to run on Macintosh and PC computers. The software requires a 1024 x 768 minimum screen resolution. The Little Phatty Operating System should be as current as possible for best results. (updates available at www.moogmusic.com) A MIDI interface is required for the software to work with the Little Phatty. A wheeled, two-button mouse is recommended for additional control of the program.
2.1 Before you begin To get the most out of this program you should be familiar with the operation of the Little Phatty. The Little Phatty Users Manual is the best resource to aid in the understanding of the inner workings of your Little Phatty. It is recommended reading for all Little Phatty owners. Although this software program can be an invaluable resource to aid in the understanding the Little Phatty, it is not a substitute for reading the Little Phatty Users Manual.

3 STARTING UP Double clicking on the Moog Little Phatty program icon launches the Little Phatty Editor Librarian program. The first launch will produce a selection window that will ask you to choose which edition of Little Phatty you own.
The program will then ask for your name and registration number as shown.
To register the software, click the Register Online button (youll need an active Internet connection for this). Clicking the Register Online button will take you to the Moog Music Online Store, where you can order the program. After completing the online transaction, the Registration code will be sent to your email address. Once you have obtained a registration code, enter this information along with your name in the appropriate fields and click the Enter Code button a small confirmation message box will appear once.

Page 7

Registered users will see their name displayed on a slightly modified splash screen that includes, This software is registered to (your name). An example for this author is shown below.
Note: In case of lost registration, a hard drive crash or other calamity, registered users can obtain their registration information by writing to info@moogmusic.com or moog@soundtower.com.
It is a good policy to burn off a copy of the setup exe along with the registration code information in a text file as well as have a paper copy of said codes in a secure place to help forestall such events. If you click on the Demo Mode button, the program will open and allow you to edit all of the Little Phatty's preset parameters and use most of Editor's functions, with the following limitations: Saving files (disabled) Loading files (disabled) with exception of SysEx (System Exclusive) files in OS UPDATE utility Writing presets to the Little Phatty (disabled) Transmitting the User Bank (disabled) Sending up to 5 panel edits from the Library and Preset Genetics to the Little Phatty The editing session is time-limited but here is no limit to the number of times the program can be run in Demo Mode.

Effectively this enables the editors Virtual Input port to receive the cc data and send it through to the MIDI ports selected as active on the MIDI interface connected to the hardware. Filters are as follows: Activate Midi Controller Port (Under MIDI IN CONTROLLER middle tab)
When selected, the physical MIDI IN (Midi Controller) is activated. This port can be used to connect Midi Controllers. The Continuous Controller data (CC) coming through this port can be mapped to control any LP Parameter via editor. Enable Midi Clock
This option passes the Midi Clock to LP from Moog LP SE V-Output Port.

Page 13

Enable Midi Notes
This option passes the Midi notes played from a LOGIC track to MOOG LP SE INPUT Port. Enable Sysex.
This option enables you send complete Preset Sysex dumps to the Midi Sequencer tracks via Moog LP SE VOutput Port. It also enables Sysex data to pass from Moog LP SE V-Output Port to MIDI Out PORT where the LP is connected Enable Editor's Controls real time update (under VIRTUAL MIDI PORTS tab)
If enabled, the editors controls (knobs and etc.) will turn and adjust accordingly when CC data is received. The graphical interface always uses some CPU processing power - on some slower systems this may produce unwanted delay. If disabled, the editor still sends mapped CC parameter change to the LP but does not show in on its graphical interface.
CC/NOTE data from and to Logic in play mode from and to editor: If a previously recorded track with cc data embedded from either/both the LP or the editor is played through the Virtual Midi port to the Editor you will see the channel number, parameter number and the parameter value listed in the record/play control of Logic and the value on the accompanying knob on the editors GUI if Enable Editor's Controls real time update is enabled. Changes on the GUI will show up in LOGICs record/play control as well.

5 PROGRAM ORGANIZATION The Little Phatty Editor Librarian program is organized as shown below. The main window is always displayed when the program is launched and becomes the starting point for all preset modifications and bank operations.

Page 15

6 PROGRAM WINDOW The Little Phatty Editor is the main program window, and is always displayed when the program is launched. This window contains three program components: the User Bank (1), the Little Phatty Panel (2), and the Librarian (3). The three program components interact and are always active. A detailed description of each program component follows.

Page 21

In the figure above we created a folder called Little Phatty Banks located on the My Documents folder in a PC XP environment, and used it to store some example bank files. Note that program bank files have the extension.mlp. When loading a bank file, the Editor Librarian program will allow you to see all file types, but only those files with an.mlp extension can be loaded as a bank. All others will be ignored. The Save button allows you to save the current bank. Upon clicking Save, youll be presented with a dialog box similar to this one:
Enter a suitable file name for your preset bank in the Save As: name field. Clicking on the Save button here will save the file to the location you specify and append.mlp to the file name. To receive a bank from the Little Phatty, click the Receive button (you can also select "Receive User Bank from the MIDI menu). The receive bank window appears. Clicking on the Start button will initiate the transfer from the Little Phattys current bank to the Editors current bank. If for some reason your MIDI interface cannot keep up with fast MIDI messages, you can adjust the timing by adding a delay in milliseconds using the scrolling adjustment:

Page 22

To transmit the User Bank from the Editor to the Little Phatty, click the Transmit button (or select "Transmit User Bank" from the MIDI menu). The transmit window appears. Clicking the Start button will transmit the contents of the current User Bank to the Little Phattys current bank. As with the Receive function, if for some reason your MIDI interface cannot keep up with fast MIDI messages, you can adjust the timing by adding a delay in milliseconds with the scrolling adjustment:
The transmitted data will be written into the current Little Phatty bank, overriding the existing presets.
Note: Although the Editor supports both Little Phatty banks, only one bank (the current bank) can be transmitted or received at a time.
6.1.3 Other User Bank Functions Now lets look at the other User Bank button functions that havent been covered.

The Edit button takes you to the Editor window, where you can edit the currently selected preset. A complete explanation of the Editor window is saved for later in this guide (see section 7). The Use loaded data checkbox is a feature that changes the way the program works with the Little Phatty. When the box is unchecked (disabled), selecting a preset from the User Bank switches the Little Phatty to the corresponding preset. The Little Phatty sends the preset to the User Bank. This guaranties synchronization between the Little Phatty and the program. When the checkbox is checked (enabled), the selected preset data from the User Bank is sent to Little Phatty's edit buffer for editing and audition. This feature helps you to browse through presets in the User Bank without the need for dumping the entire bank to the Little Phatty. The Auto Dump checkbox works for the Librarian. When checked (enabled), a selected preset from the Librarian preset list is automatically sent to the Little Phatty's edit buffer for editing/audition. When unchecked, no data is sent to the Little Phatty. The Drag and Drop and Multi Select radio buttons control the way the cursor operates:

Page 23

Drag and Drop mode is conventional cursor operation, allowing you to freely drag and drop presets between the current User Bank and the Librarian. (For Mac users: You can add the SHIFT and COMMAND ( ) modifier keys to make multiple preset selections. These can be groups of presets, nonadjacent selections, or a combination of both.) Multi Select mode locks the cursor into Select mode, allowing you to select groups of presets. This mode can be useful for large amounts of group moves because it restricts the operation of the cursor to just making selections, preventing accidental dragging of presets out of the User Bank or Librarian. In Multi Select mode, presets are moved between the User Bank and Librarian using the large Move arrows (see 6.1.5 Organizing Presets).
For PC users: click once on a preset to highlight it, while holding down the shift key click on another non congruent preset, you will then highlight all the intervening presets, inclusive of first and last clicked, ready for mass copy to Librarian. (see right image)
If you click once on a preset and then hold down the Ctrl key, each of the subsequent presets clicked will be individually highlighted. (see left image)

Page 24

6.1.4 The Bank Menu The Bank menu shown below includes the Load User Bank Data and Save User Bank Data As commands that duplicate the functions of the Load and Save buttons. It also includes commands to generate a New Bank (creates a bank of 100 default presets), load one of the Little Phatty factory banks (Tribute or Stage Factory Bank Presets) and commands to Copy, Paste, Rename and Initialize selected presets in the User Bank. A Single Parameter Adjustment command is also available here, allowing you to adjust a single parameter without opening the Editor. These commands work on the currently selected User Bank.

When moving presets from the Library to the User Bank, the presets in the User Bank will be replaced by the ones from the Library and will be transmitted to the Little Phatty bank. A dialog box will ask you to confirm this operation:
Selecting OK will copy the presets into the User Bank and transmit them to the Little Phatty. Selecting NO will copy the presets into the User Bank without transmitting them to Little Phatty. Selecting Cancel will cancel the operation. Moving multiple presets into the User Bank will replace the selected preset in the User Bank and the equal number of consecutive presets. Here is an example illustrating what this means: 1. 2. 3. 4. Select Preset No 029 in the User Bank (either bank). Select 4 non-adjacent presets from the Librarian (any category). Drag the 4 selected Presets from the Librarian and drop them into the User Bank. A warning dialog will be displayed like the one above. Selecting OK will copy the four presets into the User Bank replacing Presets 029 - 032 with the four selected Librarian presets and transmit them to the to the Little Phatty at the same locations. If you select NO then the presets will not be transmitted to Little Phatty but they will still replace Presets 029 to 032 in the User Bank. Selecting Cancel will cancel the operation.
Note: Moving a preset from the User Bank to the Librarian will not automatically assign the corresponding sound category to the preset in the User Bank (the presets sound category in the User Bank will remain unchanged). However, if a preset moved from the Librarian to the User Bank it will include the corresponding sound category.

Page 36

6.3.4 The Librarian Menu
The Librarian menu (shown on the left) includes commands that duplicate the functions of the New, Load and Save buttons mentioned above. It also includes commands to Load From User Bank Data (copies all 100 presets from the User Bank), Add From Top Offspring (copies all presets from the Preset Genetics Top Offspring list into the current category) as well as commands to Copy, Paste, Cut, Delete, Select All and Rename selected presets, and commands to Rename and Clear categories, and restore the Default Category Names.
Selecting Rename Category (or single clicking on the triangle to the left of the category name) will create a text window allowing you to change the existing category name or enter a new one:
Clicking outside of the name field will enter the new name and close the text window.
Note: Default category names match the categories built into the Little Phatty. While you can rename a Librarian category for your own convenience, doing so WILL NOT change the category name in the Little Phatty - the hardware will always use the built-in categories.
Selecting Default Category Names will restore all category names to their default designation. Selecting Clear Category will clear the contents of the selected category, leaving all other categories unaffected.

7 THE EDITOR WINDOW This is the main parameter adjustment window. Here you can delve deep into the parameters as groups or individuals, Global parameters and Pot mapping are accessed here. 7.1 The Editor Window In general clicking the Edit button on the main screen brings up the Editor window as shown below. Here you have access to every Little Phatty programming parameter, including those parameters that can only be accessed through the Little Phattys menus (Filter Poles, Pot Mapping, Keyboard and Trigger Modes, and Pitch Bend Amount). The Editors real-time controls allow you to tweak and audition the sound of your presets right from your Macintosh or PC.
Note: In addition to having any on-screen control changes update the Little Phatty, adjusting any Little Phatty control updates the onscreen display, so you can actually use the Little Phattys controls AND the Editor parameters simultaneously for the ultimate in Little Phatty preset development!

Classic Surface.

Page 38
7.2 Parameter Resolution in the Editor The Editor window can display the Little Phattys parameters in 7-bit, 8-bit or 16-bit resolution. You select the bit value from the Editors Options menu:
When 7 BIT is selected, the Editor will display all parameters values in 7-bit resolution (value range 0 127). When 8 BIT is selected, the Editor will display all parameters values in 8-bit resolution (value range 0 255). When 16 BIT is selected, the Editor will display all parameter values in 16-bit resolution (value range 0 65535).
7.3 Editing Preset Parameters Preset parameters are adjusted in the Editor window in several ways: Soft toggles/lit buttons Clicking on a toggle changes the value to the next forward or back values. The lit buttons change colors reflecting those on the Phatty. Mouse wheel movement if the cursor is placed over one of the knobs or soft toggles will change the value and make the corresponding image change as appropriate.
Note: For 8-bit resolution, valid data values are 0-255. For 16-bit resolution, valid data values are 0-65535. If you type in a value outside of these ranges, it will be ignored. (7-bit values are 0-127)
Label pull-down menus Click to pull down a menu in the Editor window. Menu selections are made by single-clicking on a menu item. This action will select that item and close the menu. Parameter groups You can copy a complete parameter group from one preset to another. Under Edit in main menu select copy:
You can then select paste at a later time after changes have been made and the entire preset as copied will be restored.

Page 39

Presets can be auditioned in the Editor window by selecting V-Piano under Options in main menu bar (or Ctrl-P in PC):

To the right of the left of the piano keyboard are the Pitch and Mod wheels. Youll find that the Editors on-screen Pitch Bend and Mod wheels work just like the real thing; the Pitch Bend wheel springs back to its center position when released, but the Mod wheel stays put when you adjust it.

Page 40

7.4 Writing Presets to the Little Phatty
The Editors Write command allows you to save an edited preset to the Little Phatty. The command is located under the Edit menu selecting Write brings up a dialog box as shown:
You can scroll through all destinations using vertical scroll bar to the right or by rolling the mouse wheel if your mouse is equipped with a mouse wheel. Click to choose a destination and then select OK to store the preset. Click Cancel to cancel the operation.

Page 41

7.5 Other Edit Menu Commands and Misc. The Editors Edit menu also contains commands to Copy, Paste, Rename and Initialize the current preset. Although largely self-explanatory, heres what they do: The Copy command copies all parameters for the current preset. The Paste command pastes all copied parameters to the current preset. The Initialization command will initialize the current preset to default parameters. The Rename command allows you to change or rename the current preset. When Rename is selected, you will be presented with a message dialog window as shown:
Clicking in the name field allows you to change the preset name up to a maximum of 13 characters. Additional characters will be ignored. Clicking OK will store the change and close the dialog box. Clicking Cancel will close the dialog box without changes.
Note: You can also bring up the Rename window by double-clicking on the preset bank in list box in the Editor.

Page 42

Clicking on the category field in the preset name window brings up a menu of sound categories, allowing you to assign a category from one of the 24 available:
All edits made in the Editor Window (parameters, name and categories) affect the preset in the Little Phattys EDIT buffer. Since the EDIT buffer is temporary, the preset will have to be stored using the WRITE command if you wish to keep it.
7.51 Little Phatty Panel Display Type The Editors Options menu contains a command to modify the Little Phattys panel settings to either Tribute or Stage Type depending on the users current model being edited. Under Option in main menu choose Display and the expanded menu will offer you a choice as seen below:

Page 43

7.6 Adjusting Visual Properties The Little Phattys Editor screen has incorporated into it a nice resizing feature to help accommodate for differing screen resolution and user on screen organizational needs. By mousing over to the lower right corner of the window until the cursor changes to the double sided arrow you may click and hold and physically resize the entire editing surface. The image is automatically scaled with no loss of resolution or functionality. You can resize from full monitor image to roughly size and have access to Librarian at the same time.

Both parent banks use the presets from the User Bank, and these banks will automatically load when the Preset Genetics window is opened. Any pair of the 100 available presets can be used for the genetics functions (one each from mother and father). The result of applying the user-selected genetics functions creates the child bank, and any keepers auditioned from the child bank can then be moved into the top offspring bank.
The four Preset Genetics functions are: Mix: The parameters of each child preset are randomly chosen from either a parameter from the mother or father source. For example, if the mothers cutoff frequency was 10 and the fathers was 88, the childs value would only be 10 or 88. Morph: The value of each parameter is linearly interpolated from one parent to the other. The first child is identical to the mother; the last child is identical to the father. All others are weighted towards each parent depending on their placement within the list. The middle child preset is exactly 12 mother and 12 father. Mutate: The parameter values of each child preset are randomly chosen from within the range between each parents parameter. For example, if the mothers cutoff frequency was 10 and the fathers was 88, the child values would be anywhere between 10 and 88. Random: The value of each parameter of each child is produced by a random number from within the min/max Little Phatty parameter range.

Page 47

Note: Experimentation by using vastly different parents and similar parents creates the most interesting results. You can also interbreed the child patches, too. In addition, you can set filters to excluded parameters that will not take a part in the generation of new offspring. Experiment and have fun!
Note: Preset names in the Kids bank also become scrambled or rearranged when you use the Genetics functions. This is normal. You can prevent preset names from changing by checking the Name box under Exclude Preset Parameters. When the Name box is checked, all preset names in the generated Kids bank will assume the selected preset name from the Mommy bank.
The Auto Audition checkbox enables automatic transfer of the selected presets from the mother, father, kids or top offspring banks to the Little Phatty's edit buffer. When the Auto Audition checkbox is unchecked (disabled), no data is transmitted to the Little Phatty. The Edit button brings up the Editor window, permitting on-screen editing of the selected preset from the mother, father, kids or top offspring banks. The Auto Audition button must be checked for the Editor to correctly display the selected preset in the Genetics window. The Reset button resets all selections made under the Exclude Preset Parameters section. When the Reset button is clicked, any checked selections become unchecked.
8.2 Single Parameter Adjustment This function allows you to change one of the preset parameters for an entire Little Phatty bank. It works similar to the Single Parameter Adjustment in the User Bank. Simply select the desired parameter from the pull-down menu:

and use the slider control to set the desired value:

Page 48

When you click OK, a new Kids bank is generated from the Mommy bank. Every preset in the Kids bank now contains the newly modified parameter. To save the change, select Replace Little Phatty Bank with the Kids Bank from the FILE menu. Clicking OK will send the Kids bank to the Little Phatty. Clicking No will not update the Little Phatty bank, but will update the Mommy bank with the changes, allowing you to make additional changes if desired.
8.3 Moving Genetics Presets Presets created in the Genetics window can be moved in several ways: Selected presets can be dragged from either the Top Offspring or Kids bank directly into any Librarian category if the Genetics Window is in front of the Main window. Selected presets can be dragged from either the Top Offspring or Kids bank directly into the User Bank. When dragging a preset to the User Bank, a message dialog will be displayed asking if you also want to write the preset to the Little Phatty's bank:
Clicking OK will send the Top Offspring or Kids preset to the Little Phatty. Selecting No will not update the Little Phatty bank, but will update the Users Bank with the change. Selecting Cancel will cancel the operation.
Note: The Preset Genetics module does not support the same multiple selection options as the Librarian and User Banks (i.e. the SHIFT and COMMAND keys have no function).

Page 49

8.4 The Preset Genetics Menus The File menu contains commands to manipulate the banks and files in the Preset Genetics window:
Save Top Offspring as Library File permits saving the complete Top Offspring bank as a separate library file, regardless of the number of presets in the bank. Paste Top Offspring to Library will copy the contents of the Top Offspring bank to the Librarian, pasting the presets into the end of the Library (unassigned) category. The Clear Top Offspring command will delete all entries in the Top Offspring bank, while leaving the parent and child banks undisturbed. Refresh Parent Banks will copy the current contents of each selected bank into each parent bank. For example, if Mommy is the A bank, and Daddy is the B bank, selecting Refresh Parent Banks will place the current contents of the A bank into the Mommy, and the current contents of the B bank into the Daddy. The Replace Little Phatty Bank with the Kids Bank command will replace the contents of the User Bank with the modified presets in the Kids Bank. When using this function you will be presented with an option to send this bank to the Little Phatty. This function will also replace the Mommy bank, allowing you to continue modifying other preset parameters. The Close command will close the Preset Genetics window and return you to the main window. Alternatively, you can also click the red button in the upper left corner.

Page 50

8.5 Morpher The Morpher function is a fun and powerful utility to smoothly transition between two programs. This function is accessed from the Editor window under the Generator menu:
A window appears with the current program loaded as initial point of reference. In the image below the initial program BASSUSGROSSUS is represented. The Morpher will, if the slider is moved, morph all individual parameters of BASSUSGROSSUS closer to that of BIG UN seen displayed in drop box to the left.
The slider will, using the morph algorithm, morph the current program, in increments that matches the resolution the editor is set to work in, from 100% BASSUSGROSSUS and 0% BIG UN through 50%/50% to ultimately 0% BASSUSGROSSUS and 100% BIG UN parameter values.

Page 51

Selecting the Keep button will set the editor to the values calculated and be given a temporary name based on the algorithm. In the image below you can see that the temporary name is: BFKFUOBFEFFGF with 66% Morphed to BIG UN parameter values completed.

9 OTHER PROGRAM FUNCTIONS 9.1 Updating the Little Phatty Operating System First make certain that MIDI connections are established and the correct MIDI Out port is selected (See MIDI Setup). To update the Little Phattys OS, you use the update function located in the Moog Little Phatty menu:
When selected the user will be prompted by a small request window:
The options above express the reality of this author selecting the Tribute mode upon initial startup of the editor. I am given a choice of updating from my internet connection (Tribute OS Update (401)) or from a sysex file I have previously downloaded and saved to my hard drive (OS Update From File).
The OS Update From File file dialog will prompt you
to open a System Exclusive file (.syx) containing the software update. You will need to locate and select the update file. When you open the file, the following message box will appear

Page 53

(The author used a 4 byte dummy file here for illustration purposes) After Start is selected the updated OS will be transmitted via MIDI connection to your Phatty. The following prompt/warning window will appear.
It is imperative that you DO NOT turn off your Phatty during this process.
Note: Some MIDI interfaces use different buffer sizes (normally between 128-65535 bytes), which could result in buffer errors when large messages like the OS update are transferred. To compensate for this, the transmitted packet size can be adjusted here to a higher or lower value. By changing the packet size, large SysEx messages can be converted into more manageable pieces for data transfer. The packet size should be only adjusted if the Little Phatty reports a checksum error after the SysEx transfer is completed.

Now set up the Little Phatty to receive the update: 1. Press the MASTER button on the Little Phatty and scroll down to select "Receive Update" 2. Press the ENTER button and the following message on the Little Phattys LCD will appear: This will delete the Operating System! Are you SURE? YES / NO 3. Use the Cursor button to select YES and press the Enter button. The Little Phatty is now ready to receive the update files. Back in the Editor, click the onscreen Start button, and wait while the data is being transferred. Do not turn off the power and do not use any other Editor controls while sending the update. The Little Phatty OS update usually contains three SysEx bank files. After the first file is transferred, repeat the procedure for the remaining files. Refer to the OS update documentation for full details on the update procedure.

Page 54

9.2 Online Help Page If you are ever stuck in your understanding or lost this file from your hard drive there is a main menu option (Help) that has a menu selection
that will open your default web browser and direct it to: http://www.soundtower.com/moog/lp/help Here you will find this file in PDF format, an online version and more information on updates that have occurred since initial release of this editor. Please check often for update information. SoundTower will direct you to the appropriate Moog page for service and help as needed.
9.3 Playing from the Computer Keyboard You can audit Little Phatty sounds using your computer's keyboard to play notes. The middle and bottom rows of computer keys act as a single octave of keys mapped like a piano keyboard. You can use these keys to remotely play notes on the Little Phatty: Notes: C Keyboard: C# D D# E F F# G G# A A# B
| s d g h j | | z | x | c | v | b | n | m | -----------------------------------------------------------------------------
Each key press generates a MIDI Note ON message corresponding to the note as specified. When the key is released, a MIDI Note OFF message is sent. You will see the Little Phattys MIDI LED blink as these commands are sent, and the Little Phatty will play the corresponding note.
Note: This feature works in all windows, allowing you to audition Little Phatty sounds at any time. Note that the CAPS LOCK key must not be ON, as only lower case letters send MIDI note data. You can use the CAPS LOCK key to temporarily turn off remote playing if desired.
Two keys are programmed to adjust octaves (increment/decrement): o Octave down (-1) p Octave up (+1) Octave switching ranges from 2 to +8 (ten octaves). When the octave switching keys are pressed, a pop-up window briefly appears showing the change:

Page 55

Tip: You can sustain a note by pressing down a note key and while it is depressed, press an octave key. A MIDI Note ON command will be sent without a corresponding MIDI Note OFF, causing a sustained, or stuck note. To un-stick the note, press the Space Bar. The Space Bar will send an All Notes Off command that shuts off all MIDI notes.

New Features

OS 2.0 introduces a number of new features and functions to the Little Phatty. To incorporate these new features in a streamlined and logical fashion, the Master Menu shown on page 6 has undergone some changes. Complete descriptions of all new Master Menu features begins on page 7. A few of the new features are not menu-based; these include an improved Preset Storage routine, enhanced MIDI Continuous Controller data handling, and a convenient Tap Tempo feature. These new features are described below. Preset Storage The Preset Save routine has been improved. As always, to save a preset you press the ENTER/STORE button while in PANEL Mode. You will see two lines on the Little Phatty display:
The top line shows the location where the preset will be saved, and the name of the preset which is currently saved in that location. No more overwriting your favorite presets by mistake! Use the VALUE knob to select a preset to overwrite, then press CURSOR to move the cursor to the lower line of the LCD. OVERWRITE:NO is the default setting. If you change your mind and do not want to save the preset, you can press ENTER and the LP will return to PANEL mode without saving. If you are sure you want to save your preset to the selected location, set OVERWRITE:YES and press ENTER.
The LP will display the PRESET STORED message to confirm that your preset was saved successfully.
NOTE: When the Arpeggiator is running, the ENTER/STORE button is used to activate the latch if the Latch parameter has been enabled. For more on the Arpeggiator and Latch functions, see page 12.

MIDI Continuous Controllers (MIDI CCs) The Modulation Wheel and Filter Cutoff parameters now send and receive high-resolution, 14-bit Midi CC messages. This allows for finer control and smoother changes, whether you are using the LP as a MIDI controller, or controlling the LP via MIDI from your sequencer. The MIDI CC channels are mapped as follows; MSB indicates the regular CC number for the parameter, and LSB indicates the high-resolution fine control. If you are only sending 7-bit MIDI CC to the LP, use the MSB channel number by itself. MOD WHEEL: FILTER CUTOFF: Tap Tempo Tap Tempo is an easy and intuitive way to adjust the speed of the LFO Rate or the Arpeggiator Clock. The Tap Tempo function is always available for any preset in PRESET Mode. Tap Tempo can be used to adjust the LFO Rate when the Arpeggiator is not running,, or adjust the Arpeggiator Clock. when the Arpeggiator is running. To enter Tap Tempo Mode, press and hold the LFO RATE button until it starts flashing rapidly; this indicates that Tap Tempo Mode is active. When Tap Tempo is active and the Arpeggiator is not running, tapping the LFO RATE button will set the internal LFO Rate and override the LFO Sync Mode (see LFO SYNC on page 8). Both the LFO LED and the LFO RATE button will begin flashing at the new rate, and the LP will display the new rate in BPM (Beats Per Minute): MSB = 1, LSB = 33 MSB = 19, LSB = 51

NOTE: The LP will always display BPM as the closest whole-number value. For example, if the actual Tap Tempo rate is 271.3 BPM, the LP will display 271 BPM as shown. The LFO will run at the actual Tap Tempo rate, however - in this case, 271.3 BPM.
When Tap Tempo is active and the Arpeggiator is running, tapping the LFO RATE button will set the rate of the Arpeggiator Clock. Both the LFO LED and the LFO RATE button will begin flashing at the new rate, and the LP will display the new rate in BPM:
(Arpeggiator unlatched view)
(Arpeggiator latched view)
If the MODULATION control knob is adjusted while in Tap Tempo Mode, it will override the Tap Tempo and adjust the LFO Rate or Arpeggiator Clock to the new value. To exit Tap Tempo Mode, press and hold the LFO RATE button until it stops flashing. This will return to the previous mode (either free running or MIDI clock).
NOTE: If the Arpeggiator is set to MIDI CLOCK when Tap Tempo is active, Tap Tempo will adjust the internal LFO Rate and not the Arpeggiator Clock.

Master Mode Menu Structure
The figure below shows the new structure of the Master Mode menus. With the exception of the Advanced Preset menu tree (shown on the right), all Master Menus specify global parameters. The Advanced Preset menus are used to program parameters for individual presets; these parameters are stored separately with each preset. New or modified menus are indicated with an asterisk (*). Descriptions of these menus follow.
The new OS 2.0 Master Menu

Page 4

Master Mode Menus
The new Master Mode menus are described below. Please refer to the LP Users Manual for all other menu descriptions. LFO SYNC: The LFO Sync menu allows you to globally set the LFO to internal or MIDI clock signals. When set to INTERNAL, the MODULATION control is used to set the rate of the LFO. When set to MIDI CLK, the LFO rate is controlled by an external MIDI Clock and the selected Clock Divider settings (see below). To change the LFO Sync Mode, use the CURSOR button to move to the selection field and use the VALUE knob to select the mode. Modes: INTERNAL, MIDI CLK; the default is INTERNAL
NOTE: For additional details, see Appendix B, LFO Sync Modes
When the LFO Sync Mode is MIDI CLK, you can program the clock divider to one of 15 different values. The divisor is based on 24 clocks per quarter note (the MIDI standard). The table below shows how the number of MIDI clocks relates to musical time values. When the LFO Sync Mode is MIDI CLK, the MODULATION control can be used to select the clock divider (the 15 divider values correspond to the 15 LEDs in the MODULATION control lightpipe). The default clock divider value is 1/4 (24 clocks/quarter note).

CLOCKS/QUARTER NOTE 192 TIME VALUE 1/32 note Dotted 1/32 note 1/16 note Dotted 1/16 note 1/8 note Dotted 1/8 note Quarter note Dotted quarter note Half note Dotted half note Whole note Whole note + quarter note Whole note + half note Whole note + dotted half note Whole note + whole note LP DISPLAY 1/32 1/32 DOT 1/16 1/16 DOT 1/8 1/8 DOT 1/4 1/4 DOT 1/2 1/2 DOT WH WH + 1/4 WH + 1/2 WH + 1/2 DOT WH + WH

TUNING TUNING now has a dedicated menu (it was previously combined with LOCAL CONTROL ON/OFF, which has been moved to the MIDI SETUP menu). The features of the TUNING function are unchanged in OS 2.0. Refer to the LP Users Manual for more information (Tribute Edition owners should refer to the OS 1.03 update document). MIDI SETUP: The MIDI SETUP menu is used to select the LPs MIDI options. There are seven pages of MIDI menus, beginning with the ALL NOTES OFF menu. This menu allows you to issue an All Notes Off message to the MIDI output, shutting off all active notes on the LP and/or any attached MIDI tone modules or keyboards. This command is the equivalent of a MIDI panic button to silence stuck notes. To issue the command, simply press the ENTER button. Although it is shown in the illustration here, you do not have to enable this menu using the CURSOR button. The second page of the MIDI Setup menu allows you to turn control of the LPs synth engine ON or OFF locally, i.e. the keyboard, wheels, and any front panel controls that can also receive MIDI. It does not disable any MIDI transmitting or receiving. A setting of OFF will prevent double triggering in the event you are using a MIDI sequencer with both the MIDI IN and MIDI OUT connected, and the sequencer is echoing MIDI data back to the LP. To change the Local Control setting, use the CURSOR button to highlight the control value, then use the VALUE knob to change the setting. Values: ON, OFF; the default is ON
The third page of the MIDI Setup menu allows you to select the MIDI input connection. Since the LP Stage II offers both MIDI DIN and USB connections, several input options are possible. To specify the MIDI input connection, use the CURSOR button to highlight the input selection, then use the VALUE knob to select the desired input. NOTE: This menu only applies to USB-equipped LPs. Values: NONE, DIN, USB, DIN/USB; the default is DIN/USB
TECH NOTE: DIN is an abbreviation for Deutsches Institut fr Normung (in English, the German Institute for Standardization). DIN connectors commonly refer to a family of circular connectors that were standardized by the DIN for commercial electronic use. When the MIDI standard was released in 1983, it specified a 5-pin DIN connector as the hardware interconnection, thus the MIDI DIN connector.

Page 6

MIDI SETUP (cont) The fourth page of the MIDI Setup menu allows you to select the MIDI output connection. To specify the MIDI output connection, use the CURSOR button to highlight the output selection, then use the VALUE knob to select the new output. NOTE: This menu only applies to USBequipped LPs. Values: NONE, DIN, USB, DIN/USB; the default is DIN/USB

The fifth page of the MIDI Setup menu allows you to select the routing of the MIDI Merge function for the USB input. When MIDI Merge is ON, the LP will echo all MIDI data received at the USB MIDI Input port to the selected MIDI Output port, merged with any MIDI data generated by the LP. This allows you to pass MIDI data thru the LP, even though the LP has no dedicated MIDI Thru connector. To change the selected MIDI output port, use the CURSOR to highlight the output parameter, then use the VALUE knob to select the desired output. NOTE: This menu only applies to USB-equipped LPs. Values: NONE, DIN OUT, USB OUT, DIN/USB OUT; the default is NONE.
The sixth page of the MIDI Setup menu allows you to select the routing of the MIDI Merge function for the DIN input. When MIDI Merge is ON, the LP will echo all MIDI data received at the MIDI DIN Input port to the selected MIDI Output port, merged with any MIDI data generated by the LP. To change the selected MIDI output port, use the CURSOR to highlight the output parameter, then use the VALUE knob to select the desired output. Values: NONE, DIN OUT, USB OUT, DIN/USB OUT; the default is NONE.
NOTE: When using MIDI Merge, take precautions to insure that you do not create a MIDI feedback loop (the output is passed back into the input and then merged with the output again), or you may experience unwanted side effects like a locked-up LP. Should this happen, cycling the power should resolve the condition, but it is best not to create a MIDI feedback loop in the first place.

Page 7

MIDI SETUP (cont) The seventh page of the MIDI Setup menu allows you to set up multiple Moog synths as a polyphonic synth stack. The settings are POLY: OFF or POLY: (#) of (##). The first number represents which note this particular LP is assigned to play, the second number sets the total number of available voices. For example, if you had an LP and a Voyager RME, you would set the LP to POLY: 1 of 2; on the Voyager RME you would go to MIDI Key Order on the Master menu and set the RME to be note 2 of 2 (note that your Voyager must also have the latest firmware installed; the current Voyager OS is version 3.3). Connect the MIDI OUT from the LP to the MIDI IN on the Voyager. You should now be able to play duophonically, with the LP sounding the first note played on the keyboard and the Voyager RME sounding the second note. If all available voices are in use, additional notes will not sound until enough keys are released to free a voice. MIDI Continuous Control numbers (MIDI CCs) are consistent between the Voyager and Little Phatty, so any parameter changes such as pitch bend and mod wheel, filter cutoff and so on, should affect all voices simultaneously. If you have two Little Phatty synths, you would connect MIDI OUT from the first one to MIDI IN on the second, then you would turn on MIDI MERGE on the second LP and connect its MIDI OUT to the MIDI IN on the first LP. Turn off LOCAL CONTROL on the first LP so that it is controlled only by the MIDI data that is shared between the two synths. If you have more than two Moog synths, connect them so that MIDI passes through each synth and the last is connected to the first; but make sure that the first synth does NOT pass MIDI through to the next, or you will create a MIDI feedback loop. The first synth in this description should always be the one on which you are playing the keys. If the first synth is an LP, make sure MIDI MERGE is turned OFF on this synth. If the first synth is a Voyager, make sure that you are connecting MIDI OUT from it to the MIDI IN on the second synth; do not use the MIDI THRU jack on the first synth, only on subsequent synths (voice 2 or higher).

NOTE: When the Arpeggiator is activated, it overrides any POLY mode settings.

SYSTEM UTILITIES: System Utilities provide a set of useful system commands, including commands to calibrate, restore factory defaults and set global system options. There are seven pages of System Utilities menus, beginning with the Version number display.
The second page of the System Utilities menu depends on which LP Edition you own. LP Stage and Stage II Edition owners will see the Headphone Volume (HP VOL) menu , which allows you to scale the headphone volume in relation to the output volume. This can be adjusted from 0 (off) to 255 (max). To change the scale value, use the CURSOR to move to the scale parameter field then use the VALUE knob to select the desired value. LP Tribute Edition owners will see the EGR Matrix display, which allows you to turn off the panel switches in the Envelope Generator (EGR) section. Turning off these switches improves the signal-to-noise ratio of the LP Tribute. This may be useful in some applications such as recording using presets with low filter cutoff values or low oscillator level values. By disabling the EGR switches, real time editing of the Volume or Filter EGR settings may still be performed with Pot Mapped panel controls, or MIDI CCs. The EGR Matrix always defaults to ON when the LP is powered up. To switch the EGR matrix off, use the CURSOR to move to the ON/OFF parameter field, then use the VALUE knob to select OFF.
The third page of the System Utilities menu allows you to enable or disable menu wrapping. When menu wrapping is enabled (ON), menus will wrap back to the beginning when you reach the end. When disabled (OFF), menus will not wrap. To enable/disable menu wrapping, use the CURSOR to move to the ON/OFF parameter field, then use the VALUE knob to select the desired value. The default value is ON.
The fourth page of the System Utilities menu allows you to perform a Master Reboot of the LP, which is similar to turning the power OFF and ON. The Master Reboot function is unchanged in OS 2.0. Refer to the LP Users Manual for more information (Tribute Edition owners should refer to the OS 1.03 Update documentation).

Page 9

SYSTEM UTILITIES (cont): The sixth page of the System Utilities menu allows you to restore the global default values, performance sets and factory presets. The Restore Factory function is unchanged in OS 2.0. Refer to the LP Users Manual for more information (Tribute Edition owners should refer to the OS 1.03 Update documentation). The seventh page of the System Utilities menu allows you perform calibration routines. The Calibration function is unchanged in OS 2.0. Refer to the LP Users Manual for more information (Tribute Edition owners should refer to the OS 1.03 Update documentation).

Advanced Preset Menus

The new Advanced Preset menus are described below. KEYBOARD PRIORITY (KB PRIOR): The Keyboard Priority menu allows you to select the keyboard priority for individual presets. The default is GLOB (global), which inherits the global keyboard priority setting from the Master KEYBD PRIORITY menu, but this can be changed to low note, high note or last note priority. To make a change, use the CURSOR to move to the priority parameter field, then use the VALUE knob to select the desired value. Values: GLOB, LOW, HIGH, LAST; the default value is GLOB ARPEGGIATOR: The Arpeggiator is exciting new addition to the LPs operating system, providing you with a wide range of musical sequence possibilities. The Arpeggiator is programmed for each preset individually thru the seven menu pages described here. The Arpeggiator is activated from the front panel (see Activating the Arpeggiator and Latch). To enter the Arpeggiator Menu, use the CURSOR to highlight ARPEGGIATOR and press ENTER.
When you enter the Arpeggiator menu, the top line of the display changes to indicate that you are now programming the Arpeggiator. The first page of the Arpeggiator Menu allows you to enable the arpeggiator function for the chosen preset. When ON is selected, the arpeggiator is armed and ready to be switched on from the front panel. When OFF is chosen, the arpeggiator will remain off, preventing you from switching it on accidently. To change the Enable status, use the CURSOR to move to the ON/OFF parameter field, then use the VALUE knob to select the desired setting.

Page 10

ARPEGGIATOR (cont): The second page of the Arpeggiator menu allows you to select the Arpeggiator Clock Source. There are three possible clock sources: INT - The Arpeggiator Clock LFO - The LPs Low Frequency Oscillator MIDI - An externally applied MIDI Clock When INT is selected as the clock source, the Arpeggiator runs from its own internal clock. In this mode, when the Arpeggiator is switched ON the Arpeggiator Clock rate is adjusted either with the MODULATION knob, or by using the Tap Tempo function, or by issuing a MIDI CC#90 command. Note that you must select the LFO RATE switch when the Arpeggiator is ON in order to use the MODULATION knob to change the Arpeggiator Clock rate (the MODULATION control does not adjust the speed of the LFO when the Arpeggiator is running). When LFO is selected as the clock source, the Arpeggiator is driven from the Low Frequency Oscillator. In this mode, the MODULATION knob adjusts the speed of the Arpeggiator Clock and the LFO Rate together, making it possible to get synchronous, arpeggiated LFO effects. When MIDI is selected as the clock source, the Arpeggiator is driven from an externally applied MIDI Clock. In this mode, the MIDI Clock synchronizes the Arpeggiator to the sending device (a software DAW, for example). Note that if no MIDI Clock signal is present, the Arpeggiator will not run and no notes will be heard.

NOTE: For additional details, see Appendix C, Arpeggiator Clock Source.
The third page of the Arpeggiator menu allows you to specify the Arpeggiator Clock Divider. The available Arpeggiator Clock Divider values are the same as the LFO Clock Divider (see table on page 7). To make a selection, use the CURSOR button to move to the divider parameter field, then use the VALUE knob to select the desired divisor value. The default clock divisor value is 1/4.

Page 11

ARPEGGIATOR (cont): The fourth page of the Arpeggiator menu allows you to select the range of the arpeggiator, specified in octaves. Up to +/- 3 octaves can be selected, which allows you to create sequences that are beyond the range of the LPs 3-octave keyboard. To make a selection, use the CURSOR button to move to the octave parameter field, then use the VALUE knob to select the desired octave value. Values: -3, -2, -1, 0, 1, 2, 3; the default value is 1.
The fifth page of the Arpeggiator menu allows you to select the order (pattern) in which notes are sequenced. The choices are: UP - Notes are arpeggiated from lowest to highest DN - Notes are arpeggiated from highest to lowest ORDER - Notes are arpeggiated in the order played To make a selection, use the CURSOR button to move to the pattern parameter field, then use the VALUE knob to select the desired pattern. The default value is UP.
The sixth page of the Arpeggiator menu allows you to select the Arpeggiator mode. The choices are: LOOP - When the arpeggiator reaches the end, it loops back to the starting point. BACK-FORTH - When the Arpeggiator reaches the end it reverses direction and returns to the starting point. ONE-SHOT - The arpeggiator makes one pass and then stops. To make a selection, use the CURSOR button to move to the mode parameter field, then use the VALUE knob to select the desired mode value. The default value is LOOP. The seventh page of the Arpeggiator menu allows you to enable or disable the Latch function. The Latch allows the Arpeggiator to keep repeating the arpeggio state when you remove your hands from the keyboard. The Latch menu arms the Latch function the same way the Arpeggiator ON/OFF menu arms the Arpeggiator. When the Latch parameter is set to ON, the Latch can be activated from the front panel (to activate the latch, you must be in PRESET Mode when the Arpeggiator is running - see Activating the Arpeggiator and Latch for more). When OFF is selected, the Latch is always off and cannot be activated accidently. To enable/disable the latch function, use the CURSOR button to move to the latch parameter field, then use the VALUE knob to change the latch status. The default value is OFF.

Page 12

Activating the Arpeggiator and Latch
Turning the Arpeggiator ON/OFF When a preset has the Arpeggiator function enabled, you turn the Arpeggiator ON and OFF by pressing the VALUE encoder switch (Note: you must be in PRESET mode, not MASTER mode). When the Arpeggiator is ON, an A will appear on the bottom line of the display:
With the Arpeggiator ON, any note or group of notes you play will be sequenced according to the settings in the Arpeggiator menu. To turn the Arpeggiator OFF, simply press the VALUE encoder. The Arpeggiator will switch OFF and the display will revert to the previous view:
NOTE: In previous versions of the Little Phatty OS, the VALUE encoder switch was used to advance presets. In OS 2.0, the VALUE encoder switch operation has been changed to activate the Arpeggiator exclusively. The VALUE encoder switch is still used in MASTER Mode to step through the presets in Performance Sets. Note, however, that if a preset selected from the MASTER Mode Performance Sets has the Arpeggiator function enabled and you wish to turn the Arpeggiator ON for that preset, you will need to return to PRESET Mode first, and then press the VALUE encoder switch to activate the Arpeggiator.
Turning the Arpeggiator Latch ON/OFF When the Latch function is enabled in the Arpeggiator menu and the Arpeggiator is switched ON, pressing the ENTER/STORE button turns the Latch ON. When the Latch is ON, an L will replace the A on the bottom line of the display:
As long as the Latch is ON, the Arpeggiator will keep looping in its current state. Any new note or group of notes will initiate a new note sequence based on the Arpeggiator Menu settings. If any notes are played and held while the Latch is ON, playing additional notes adds to the current list of notes to be arpeggiated. If all notes are released, the first new note played will initiate a new note sequence. To turn the Latch OFF, simply press the ENTER/STORE button. The Latch will switch OFF and the L in the display will be replaced by an A, indicating that the Arpeggiator is still active:

Updating the Operating System
Follow these steps to update the Little Phatty Operating System: 1. Connect your computer interface to the LPs MIDI In and Out jacks. 2. Power up the Little Phatty and your computer, and confirm that the computer is sending MIDI data to the Little Phatty. 3. Start the MIDI SysEx software program on your computer. 4. For PC Users: If you are using a Windows PC, run the executable firmware loader, LP_T_200.exe for the LP Tribute edition or LP_S_200.exe for the Stage edition. This program will open in a plain text window and will display a numbered list of all available MIDI OUT ports on your computer. If you do not see a numbered list of MIDI Output devices, then you do not have your MIDI interface configured correctly. Check to make sure that the latest device drivers are installed. Otherwise, at the prompt Select MIDI out device-> type the number corresponding to the MIDI Output device which is connected to your LP, and press Enter.
NOTE: It is important to only use the appropriate OS firmware for this update. Do not attempt to use the Stage Edition firmware with the Tribute Edition, and vice versa. Doing so may render the instrument inoperable.

Page 15

You should see the message Sending XXX bytes (the actual number of bytes depends on the LP Edition firmware). There will be a delay as the data is sent to your LP. On the Little Phatty display, you should see the message RX FIRMWARE, STAGE 1, followed by a series of additional firmware stages (STAGE 2, STAGE 3, etc.). When the update is complete (in about 30-45 seconds), your Little Phatty will restart automatically. When you see the LP restart, proceed to step 5. For Macintosh Users: Launch SysEx Librarian and make sure it is configured for your MIDI interface. Locate the appropriate SysEx file containing the new LP firmware; it will be called either LP_T_200.syx (for the Tribute edition) or LP_S_200.syx (for the Stage edition). Drag this file into the SysEx Librarian playlist, then select it and click on the PLAY button in the upper right corner. SysEx Librarian will transfer the firmware data to your LP. During the transfer, you should see the message RX FIRMWARE, STAGE 1 on the LP display, followed by a series of additional firmware stages (STAGE 2, STAGE 3, etc.). When the update is complete (in about 30-45 seconds), your Little Phatty will restart automatically. When you see the LP restart, proceed to step 5. 5. The LPs startup screen will display the new version of the operating system. You will see Rev: 2.00T for the Tribute Edition, and Rev: 2.00S for the Stage Edition:
To complete the installation, you must now perform a Factory Restore to load all of the correct default values for the new operating system. This operation will reset all patches in memory to the LP factory sounds, so be sure that you have saved any custom sounds to your computer before doing a Factory Restore. To perform a Factory Restore: A. B. C. D. Press MASTER Scroll to the SYSTEM UTILITIES menu using the VALUE encoder knob Press the CURSOR button and scroll to RESTORE FACTORY Press ENTER, select YES, and press ENTER.

6. Your LP firmware update is complete. You can now reload your presets and explore the new functions and features that OS 2.0 offers!
NOTES: If you have any questions about this procedure or if the update does not go smoothly, contact techsupport@moogmusic.com or call 800-948-1990 (within the USA) (+1-828-251-0090 worldwide).

Appendix B - LFO Sync Modes
There are two LFO Sync Modes: Internal (INTERNAL) and MIDI Clock (MIDI CLK). Detailed descriptions of these modes appears below. INTERNAL: When the LFO Sync Mode is set to INTERNAL, the LFO rate is controlled directly via the MODULATION knob (when the LFO RATE panel button is selected), or by Tap Tempo, or by sending a MIDI CC#3 command with a value between 0-127 (MIDI CC#3 controls the LFO RATE). When the Tap Tempo function is engaged, the internal LFO Rate is adjusted directly by tapping the LFO RATE button. You can also adjust the LFO rate using the MODULATION control as normal, and this will override the rate set by Tap Tempo (to indicate this, the Little Phattys display changes from LFO XXX BPM to the usual PANEL ACTIVE message). Note that the LFO RATE panel button will continue to blink, indicating that Tap Tempo is still active - you can tap in a new tempo at any time. To disengage Tap Tempo mode, press and hold the LFO RATE button. The LFO Rate will remain at the last rate you selected.
MIDI CLK: When the LFO Sync Mode is set to MIDI CLK, the LFO rate is synchronized to incoming MIDI Clock pulses, with one LFO cycle equal to the note duration set by the LFO SYNC CLOCK parameter (see page 7). The Little Phatty must have a MIDI Input enabled in the MIDI Setup menu in order to receive MIDI Clock. The Little Phatty Stage II has both USB and standard DIN MIDI inputs, and can receive MIDI Clock signals on either input. It is recommended not to send different clock signals to both inputs simultaneously, unless you want some very strange LFO signals to result! If you change the Sync Mode from Internal to MIDI Clock while the LP is not receiving a MIDI clock signal, the actual LFO rate does not change right away; it will continue at the same rate. However, the LFO rate is no longer being controlled by the internal LFO clock. This means that if you try to control the LFO Rate from the panel knob or send a MIDI CC# 3 message while the LFO Sync Mode is set to MIDI CLOCK, the actual rate of the LFO will not change. NOTE: These actions still update the internal LFO Clock rate parameter, but this parameter is offline while the LFO Sync MODE is set to MIDI Clock. If you change the LFO Sync Mode back to INTERNAL, the rate of the LFO will jump to the internal LFO Clock rate. If the LFO is synchronized to a MIDI Clock pulse and the MIDI Clock is stopped, the LFO will continue at the last MIDI Clock rate it received. If you hear a change in the rate of the LFO when you stop sending a MIDI Clock signal, it is a sign of jitter or instability in your MIDI Clock source. The Little Phatty performs a running average of the clock pulses it receives, so the more stable your MIDI Clock source, the smoother the resulting LFO waveform will be. Very unstable clock sources can cause distortion in the LFO waveform, due to the constant LFO Rate corrections required to stay in sync with an unstable timing signal. When the Tap Tempo is engaged and a valid tempo is tapped in, Tap Tempo overrides MIDI Clock sync for the LFO. The LFO reverts to the MIDI Clock rate when Tap Tempo is disengaged.

Page 17

Appendix C - Arpeggiator Clock Source
There are three Arpeggiator Clock Sources: Internal (INTERNAL), LFO, and MIDI Clock (MIDI). Detailed descriptions of these clock source options appears below. INTERNAL: When the Arpeggiator Clock Source is set to INTERNAL, the Arpeggiator runs at the internal Arpeggiator Clock rate. This defaults to the clock rate saved in the currently-active preset. You can change the internal Arpeggiator clock rate by using the MODULATION control, or by Tap Tempo, or by sending a MIDI CC#90 command with a value in the range 0-127. While the arpeggiator is running, you can change its internal clock rate by selecting the LFO RATE panel button and adjusting the MODULATION control. The lower line of the Little Phatty LCD will display ARP XXX BPM, showing the tempo of the arpeggiator clock. Note that due to the shared controls, you cannot use the MODULATION control to adjust the internal LFO Rate while the Arpeggiator is running in this mode. However, you can still adjust the LFO Rate remotely by sending a MIDI CC#3 command. When the Tap Tempo function is engaged, the Arpeggiator Clock is adjusted directly by tapping the LFO RATE button. You can also adjust the Arpeggiator Clock using the MODULATION control (provided that prior to enaging Tap Tempo, the MODULATION control was set to adjust the Modulation Rate and not the Amount). Adjusting the Arppeggiator Clock in this manner will override the rate set by Tap Tempo. Note that the LFO RATE panel button will continue to blink, indicating that Tap Tempo is still active - you can tap in a new Arpeggiator Clock at any time. To disengage Tap Tempo mode, press and hold the LFO RATE button. The Arpeggiator Clock will remain at the last rate you selected. LFO: When the Arpeggiator Clock Source is set to LFO, the Arpeggiator rate is defined as one whole note per LFO cycle. Unlike Internal mode, you can adjust the internal LFO Rate directly from the panel while the Arpeggiator is running. The Arpeggiator Clock Divider (CLK DIV) determines how many notes the Arpeggiator plays per LFO cycle. Note that you can still choose either Internal or MIDI Sync to be the LFO Clock source, independent of this setting. The Arpeggiator will follow the LFO rate in either case. MIDI: When the Arpeggiator Clock Source is set to MIDI, the Arpeggiator rate is directly synchronized to incoming MIDI clock. If there is no MIDI clock signal present, the arpeggiator will not play (and in fact, you will not hear any notes from the LP keyboard!). The Arpeggiator Clock Divider (CLK DIV) determines how many notes the Arpeggiator plays per measure.

PERFORMANCE TIPS: 1. When the Arpeggiator Clock Source is set to INT, you can use the Tap Tempo function to get clock rates that fall outside the minimum and maximum rates available from the MODULATION control. 2. When the Arpeggiator Clock Source is set to MIDI, if the Latch is enabled and a latched arpeggio pattern is playing, you can stop the MIDI clock and the pattern will stop playing; when you restart the MIDI clock, the latched pattern is retained and it will resume playing again.

Page 18

Appendix D - Additional Suggestions Using the Arpeggiator
Here are a few helpful ideas for using the Arpeggiator: 1. When the LPs MIDI output is enabled and the Arpeggiator is running, MIDI Note data is transmitted on the LPs MIDI Out jack. This allows you to connect additional MIDI instruments (such as the Voyager, RME, another LP, or any MIDI keyboard or Tone Module) and have all instruments play the same pattern (this requires the receiving instruments to be set up to accept MIDI Note data on the correct MIDI channel). 2. If you have a MIDI/CV converter, the LPs sequenced MIDI data can be converted to control voltages, allowing you to interface with Moogerfoogers or other CV equipment. This allows you to get synchronous effects with the LP. 3. No MIDI/CV converter? If you have a Voyager and a VX-351 Expander, you can connect the Voyager to the LP via MIDI, and use the Voyager/VX-351 combo to create the CVs for your Moogerfoogers.
