Whats New In Version 2

The big changes are the Sync and Free Play Styles, and complete our initial vision for the Rang III Phrase Sampler. With them you can play up to 4 loops at the same time, and each loop has its own volume control. In addition to the new Play Styles, we added some requested features. 1) stutter start a loop. Sort of like this, this, this loop is a gas. - See Section 13, Once & Stuttering. 2) the ability to create smooth, seamless drone loops - See Section 13, Stack & Droning. 3) the ability to easily record a loop but not play it - See Sections 10.3 and 11.3. 4) stacking on a loop playing at half speed - See Sections 10.3 and 11.3.
NOTE - 1) To help owners with a Version 1 pedal, the following symbol will appear by new Version 2 material: 2) New Rang III owners are encouraged to learn how Serial and Serial-Sync Play Styles work before trying Sync and Free.

Quick Start

So you dont want to read this beautiful manual. You want to start looping RIGHT NOW. OK, OK. Heres the low down in as few words as I can manage. This section describes the way your Rang III Looper works right out of the box. Right out of the box the 2 Bonus buttons, yellow and green, work like this: Stack hold the yellow Bonus button Erase tap the yellow Bonus button Once hold the green Bonus button Undo/Redo tap the green Bonus button Later, if you want to change the Bonus button assignments, its easy to do. See Sections 8 and 9.

Recording with master Loop 3. 1) The master loop must be playing when the slave loops are recorded. If it is not playing, it will start automatically when a slave loop begins recording. 2) When recording a slave, a loop button tap arms the loop to record at the next master restart. For example, if master Loop 3 is playing and Loop 2 is tapped, it blinks dim slow. When the master reaches its end and starts over, Loop 2 turns on bright and begins recording. A second tap of Loop 2 arms it to stop recording and it blinks dim slow. The next time the master restarts, Loop 2 becomes bright, concludes recording and plays. Playing with master Loop 3. 1) Loop 3 can play along with any other loop, or by itself. 2) If no loops are playing, then loops 1, 2 and 4 play just like there is no master. 3) If Loop 3 is playing, slave loops will start on a Loop 3 restart. For example, if Loop 3 is playing and Loop 1 is tapped, it starts blinking dim slow. On the next restart of Loop 3, Loop 1 will become bright and play along with Loop 3. 4) Pressing a loop button stops playback immediately. If Loops 1 and 3 are playing, press Loop 1 and it stops immediately and becomes dim. Loop 3 continues to play.
Stacking with master Loop 3. 1) If a slave loop and master Loop 3 are playing and Stack is pressed, stacking is active on the slave, not the master. 2) To stack on master Loop 3, play it by itself. 3) If master Loop 3 is playing by itself and stacking is active, when a slave loop plays, stacking will continue on master Loop 3, not the slave. Once with master Loop 3. Once works the same as in Serial Play Style with one exception. If master Loop 3 and a slave are playing, both loops will stop when the slave reaches its end. Also read Sections 10.3 and 11.3, Recording with the Once function. Octave with master Loop 3. If Loop 3 and another loop are playing, press Octave and both loops will play at half speed and sound an octave lower. Another press of Octave restores both loops to full speed playback. Reverse with master Loop 3. Reverse works like Octave. If 2 loops are playing, press Reverse and both will reverse direction. Another press of Reverse restores both loops to forward playback. Play-Stop All. Play-Stop All was designed for starting & stopping multiple loops. See Section 10.7 for more. Fade with master Loop 3. Fade works as you would expect. If 2 loops are playing, both master and slave loops will be affected. Section 10.8 has more details. Erase, Reverse Solo, Undo/Redo and Copy with master Loop 3. The behavior of these functions is unchanged when using the Serial-Sync Play Style.

7.3 SYNC Play Style

Loop 3 is master & the other loops are slaves. All loops can play at once.
How to Use Sync With no loops recorded, and the Sync & Free lights dimly lit, tap Loop 3 to record your first loop. The Free light turns off and the Sync light becomes bright. Sync is identical to Serial-Sync except all the loops can play at once, and this leads to more possibilities. Recording loops. Recording follows the Serial-Sync rules, but has additional possibilities. 1) A slave loop can be recorded while 2 or more other loops play. 2) A loop can be queued to record and 2 or more queued to play on the next Loop 3 restart. Playing loops. Playing follows the Serial-Sync rules, but has additional possibilities. 1) Any combination of Loops 1-4 can play simultaneously. 2) More than 1 loop can be queued to play. 3) If Loop 3 isnt playing, and a loop is queued to play, it will play the next time any loop restarts. 4) One loop can be queued to play and another queued to record on the next Loop 3 restart.

7.4 FREE Play Style

There is no master. All loops can play at once, in an independent fashion.
How to Use Free With no loops recorded, and the Sync & Free lights dimly lit, tap Loop 1, 2 or 4 to record your first loop. The Sync light turns off and the Free light becomes bright. This Play Style leads to Alices Wonderland. There are no restrictions or constraints on when you record or play loops. Anything goes. Its the 60s again, dude! Recording The First Loop This is identical to the behavior described in Section 7.1, Recording The First Loop. Recording Second & Subsequent Loops Tap another loop button to record that loop. 1) Lets say Loop 2 is recording. Tap Loop 3 and Loop 2 immediately concludes recording and plays. Loop 3 starts recording and turns on bright. 2) If Loop 2 is playing, tap Loop 3 and Loop 3 turns on bright and begins recording. Loop 2 is completely indifferent to whats happening with its neighbor, and plays on. 3) If Loop 2 is stacking, tap Loop 3 and nothing happens. A loop cannot be recorded while stacking on another loop.
Cancel recording. Using example 3 above, lets say you change your mind about recording another loop. Press Erase and the partially recorded Loop 3 is discarded and turns off. Loop 2 continues playing. Play Rules This is easy; there are no rules. You may start, stop, record or erase any loop at any time. Stop Rules Do I have to repeat myself!? There are no rules.

8. Bonus Buttons

10.2 Erase - Assignable to either Bonus button & controlled by a tap or hold
NOTE - A loop cannot be erased while it is playing, stacking or queued to play or stack.
SETUP - Loops 1-3 have been recorded but are not playing. They all are dim.
Erase Select - Select one loop to erase. Lets say Loop 2 is playing. Press Erase and it blinks fast.
Loops 1 and 3 start blinking dim fast. Tap Loop 1 and it is erased and turns off. Loop 3 and Erase stop blinking. Loop 2 continues playing throughout. Cancel Erase Select. If, in the previous example, Erase is pressed rather than Loop 1, Loops 1 and 3 return to dim and Erase stops blinking. Erase All - Erase multiple loops at once. This only applies when all loops are stopped. Hold down Erase and all loops are erased and turn off. Erase Record - Press Erase while a loop is recording to abort the recording. If Loop 1 is recording and Erase is pressed, recording stops immediately and all information is discarded so Loop 1 is empty. ** Erase works differently depending on how it is assigned. There are 3 options. ** 1) If Erase shares a button with any function other than Stack, it can only activate Erase Select. The Erase All function is unavailable. This is true regardless of whether Erase is controlled by a tap or a hold. 2) If Erase shares a button with the Stack function, its behavior is expanded. If all loops are stopped, Stack has no meaning, so holding the button will erase all loops. A tap activates Erase Select. This behavior is present regardless of whether Erase is controlled by a tap or a hold. 3) If Erase is assigned to the tap and hold actions of the same button, then it can be tapped or held at any time. Tapping activates Erase Select, and holding erases all loops that are not playing.
NOTE - The Erase All function is only available if Erase is assigned to a Bonus button by itself OR shares a Bonus button with Stack.

10.3 Once

- Assignable to either Bonus button & controlled by a tap or hold
The Once function now has additional properties as described in Section 13, Once & Stuttering. SETUP - Loops 1-3 have been recorded and are dim. Loop 3 is NOT a master loop. Arm a loop to stop when its end is reached. If Loop 2 is playing, press Once. Loop 2 and Once begin blinking fast. When Loop 2s end is reached, it stops playing and becomes dim. Once stops blinking. Cancel the once function. 1) If Loop 2 is armed to stop and Once is pressed before Loop 2 reaches its end, the Once function is canceled. Loop 2 and Once stop blinking, and Loop 2 plays on. 2) If Loop 2 is armed to stop and Loop 2 is tapped, Loop 2 stops immediately and becomes dim. The once function is canceled and Once stops blinking. 3) If Loop 2 is armed to stop and Loop 1 is tapped, the Once function is canceled. Loop 2 and Once stop blinking. Loop 1 is queued to play and begins blinking dim slow. Playing a loop once - one shot playback. Press Once and it begins blinking fast. Then tap Loop 2. It blinks bright fast and plays through one time only. When its end is reached, Loop 2 stops playing and becomes dim. Once stops blinking. Recording with the Once function. If you want to record a loop, but not play it, we have you covered. Tap Loop 1 and it becomes bright and begins recording. Press Once and it blinks fast. Tap Loop 1 to conclude recording. It is captured, but does not play.

10.4 Octave

NOTE - Octave cannot be turned on while stacking.
Change the speed of a playing loop. With a loop playing, press Octave and the loop plays at half speed, the pitch drops one octave and Octave blinks slow. Return to full speed playback. Press Octave and the loop returns to full speed playback; Octave stops blinking. Play a loop at half speed. With no loops playing, press Octave and it blinks slow. Tap Loop 1 and it plays at half speed. Recording with the Octave function. 1) Record a loop at normal speed and have it playback at half speed. Tap Loop 1 to start recording and it turns on bright. Press Octave and it blinks. Tap Loop 1 to conclude recording and your loop plays back at half speed and sounds an octave lower. 2) Record a loop at half speed and have it playback at full speed. Press Octave before recording a loop and it blinks. Tap Loop 1 to start recoding and it turns on bright. Press Octave and it stops blinking. Tap Loop 1 to conclude recording and Loop 1 plays back at full speed. Your tune plays twice as fast and sounds an octave higher. Doubling record time. Record and playback with Octave on and the pitch & speed of your loop will be unchanged, but your maximum record time will be doubled! Look at Section 22, Maximum Record Time.
10.5 Reverse - Assignable to either Bonus button & controlled by a tap or hold
NOTE - Reverse cannot be turned on or off while stacking.
SETUP - Loops 1-2 have been recorded and are dim. Change the direction of a playing loop. With Loop 1 playing, press Reverse and the Loop 1 immediately reverses playback direction. Reverse blinks slow. Return to forward playback. Press Reverse again and the Loop 1 returns to forward play. Reverse stops blinking. Play a loop in reverse. With no loop playing, press Reverse and it blinks slow. Tap Loop 2 and it turns on bright and plays in reverse. Reverse continues to blink. Recording with the Reverse function. Assume Loop 3 is empty. Press Reverse and it blinks slow. Tap Loop 3 and it becomes bright and starts recording. Tap Loop 3 a second time and the new loop plays in reverse.
The Reverse function has no immediate affect when recording a loop. It can be freely turned on and off before or during recording, but only takes affect if it is on when recording is concluded and playback begins. Then your loop will play in reverse.

10.6 Reverse Solo - Assignable only to the green Bonus button & controlled by a tap.
NOTE - Reverse Solo cannot share the green Bonus button with another function, so a hold does nothing.
1) Tap Reverse Solo and the sound of your instrument is turned off, Reverse Solo blinks bright and the Thru Mute light turns on dim. Any loop that is playing or stacking continues. 2) On the second tap your sound is played back in reverse. The time between taps sets the length of the reverse buffer. This is the length of time that your sounds are recorded before playing back in reverse. The light above the Reverse Solo label blinks once each time through the buffer. Your Rang III will continue to simultaneously record and play backwards until a third tap. 3) On the third tap the effect is turned off and the sound of your instrument is heard normally. Reverse Solo stops blinking and thru Mute light returns to its previous state. When using this effect it is recommended that the length set by two taps is related to the tempo of the music. One measure is a good place to start.
NOTE - 1) The reverse buffer (time between taps) is limited to 8 seconds. 2) Reverse Solo cannot play loops backwards; it is a sound effect like tremolo or chorus. Use the Reverse function to play your loops backwards.
10.7 Play-Stop All - Assignable to either Bonus button & controlled by a tap or hold
NOTE - Play-Stop All is specifically designed to be used when Loop 3 is acting as master. It can start and stop two or more loops at once.
Stopping all loops at once. When one or two loops are playing, pressing Play-Stop All immediately stops all loops. Starting 2 or more loops at once. If Loop 3 is master and no loops are playing, Play-Stop All can start a slave loop and the master together. For example, when no loop is playing press PlayStop All and it starts blinking slow. Tap Loop 2 and Loop 2 and master Loop 3 start playing together and turn on bright. Play-Stop All stops blinking.
NOTE - Play-Stop All cant be used if a loop is being recorded. If it is waiting on a loop selection, indicated by Play-Stop All blinking, and recording is begun, the function is canceled and Play-Stop All turns off.
10.8 Fade - Assignable to either Bonus button & controlled by a tap or hold
NOTE - 1) Fade cannot be turned on while a loop is stacking, recording or queued to record. And stacking and recording cannot be initiated during a fade.
2) Fade time is set with the knob labeled Fade Time. Makes sense to me. The time can be set from about 3 to 43 seconds. Fade time cannot be changed while a fade is in progress. SETUP - Loop 2 has been recorded. Start a smooth fade out. Press Fade and which ever loop is playing will fade to silence according to the selected fade time. When the level reaches zero the loop will stop playing. Lets say Loop 2 is playing. Press Fade. Loop 2 blinks bright slow and Fade blinks slow. Loop 2s volume begins decreasing. When Loop 2s volume reaches zero, it stops playing and becomes dim. Fade stops blinking. Start a smooth fade in. If no loop is playing Fade can initiate a fade in. For example, press Fade and it starts blinking slow. Tap Loop 2 and it blinks bright slow and begins fading in. When Loop 2 reaches full volume, both it and Fade stop blinking. Changing fade direction. If a loop is fading, either in or out, pressing Fade will reverse the direction of the fade. The rate of change, in the loops volume, will be unaffected.

Canceling a fade. Pressing the loop button of the fading loop will terminate the fade. If the loop is fading out, it will stop playing. If it is fading in, it will jump to full volume and continue playing. In either case Fade will stop blinking.
10.9 Undo (Redo) - Assignable to either Bonus button & controlled by a tap or hold
Mute the last part stacked on a loop (Undo). After stacking, press Undo and the last sounds stacked will be removed from the loop, and Undo will blink slow. The last sounds stacked is defined as all recorded sounds between two presses of Stack. Restore a muted part (Redo). Press Undo while it is blinking and the part is restored so it is heard again. Undo stops blinking. When Undo/Redo wont work. 1) If the stack function is used again, the previously stacked part can no longer be disabled or enabled. A) If Undo is NOT blinking when stack is used again, the previously stacked part becomes a permanent part of its loop. B) If Undo is blinking when stack is used again, the previously stacked part is lost and cannot be recovered. Undo stops blinking. 2) If stacking is active and you move from one loop to another, the material stacked on the first loop becomes permanent and cannot be undone. The Undo function now applies to what you are stacking on the second loop. 3) If a part is stacked while Undo is not assigned to a Bonus button, the part will not respond to Undo if it is assigned later.
NOTE The last stacked part can still be turned on or off after playing or recording other loops.
10.10 Copy - Assignable to either Bonus button & controlled by a tap or hold
The Copy function can be used two different ways. Copy Loop Used this way you can copy the contents of one loop to another, and it happens almost instantaneously. Follow these steps: 1) press Copy and it blinks fast. 2) tap the button of a loop thats NOT empty. This is the source loop. 3) tap the button of an empty loop. This is the destination loop. Voila! Its done and the new loop turns on dim. Copy stops blinking. Cancel the copy function. If Copy is pressed any time before the destination loop button, Copy stops blinking and the Copy function is canceled. Restrictions on Copy loop. You cannot use Copy Loop to duplicate a loop that is stacking or currently being recorded, however the source loop may be playing or idle. Copy Live ( Re-sampling ) Its easy to understand this use if you think of it as simply re-routing the IIIs output to the empty loop you select. Whatever is coming out of your Rang III will be recorded in the new loop. This is called re-sampling by some folks. Follow these steps: 1) press Copy and it blinks fast 2) tap an empty loops button (destination) and that loop immediately starts recording whatever is coming out of your Rang III. Copy blinks slow and the loops light turns on bright. 3) tap the same loops button to conclude recording and it turns on dim. Copy stops blinking. SETUP - Loop 1 is playing and Loop 3 is empty. Copy a playing loop. 1) Press Copy and it starts blinking fast, waiting for a loop selection. Tap Loop 3 and it turns on brightly and recording begins. Copy blinks slow. 2) Tap Loop 3 to conclude recording and it becomes dim. Copy stops blinking. Loop 1 plays through all of this. Loop 1 and anything you played are recorded on Loop 3.

NOTE This section will describe only the differences in behavior from the Serial and Serial-Sync Play Styles described in Section 10. Erase, Reverse Solo, Undo and Copy behave exactly as they do in Serial and Serial-Sync Play Styles.
The following 11 functions can be assigned to and controlled by the two Bonus buttons. This provides a way to customize the operation of your Rang III. The functions are activated by either tapping or holding the Bonus button to which they are assigned.

11.1 Stack

SETUP - Loops 1-3 have been recorded and are all playing, so they are brightly lit. Stacking on a loop. Press Stack and it blinks fast, waiting for a loop selection. Tap Loop 2 and stacking on Loop 2 begins. Stack changes to a slow blink. Stop stacking. Press Stack and stacking is turned off. Stack stops blinking. Since the III can only stack on one loop at a time, theres no need for a loop selection.
NOTE When master Loop 3 and slaves are both playing, you cannot select the master for stacking.
11.2 Erase - Erase behaves the same in all Play Styles, and is described in Section 10.2 11.3 Once
- Assignable to either Bonus button & controlled by a tap or hold Once can have additional properties as described in Section 13, Once & Stuttering. SETUP - Loops 1-3 have been recorded. Arm loops to stop at their ends. With Loops 2 and 3 playing, press Once and Once blinks slow, waiting on a loop selection. Tap Loop 2 and it and Once blink fast. When Loop 2 reaches its end, it becomes dim and stops playing. Once stops blinking if no other loops are armed to stop. Loop 3 plays on. Cancel the once function. 1) If Loop 2 is armed to stop, it and Once are blinking fast. Press Once and Once blinks slow waiting on a loop selection. Tap Loop 2 and the Once function is canceled for Loop 2. Once stops blinking if no other loops are armed to stop. Loop 2 plays on and on and. 2) If Loop 2 is armed to stop and Loop 2 is tapped, it stops immediately and becomes dim. The Once function is canceled and stops blinking if no other loops are armed to stop. Playing a loop once - one shot playback. Press Once and Once begins blinking slow. Then tap Loop 2 and it and Once blink bright fast. Loop 2 plays through one time only. When its end is reached, Loop 2 stops playing and becomes dim. If no other loops are armed to stop, Once stops blinking; but if other loops are armed to stop, their lights and Once continue to blink bright fast. Recording with the Once function. If you want to record a loop, but not play it, you can do it. Tap Loop 1 and Loop 1 begins recording and turns on bright. Press Once and Once blinks slow. Tap Loop 1 to apply the Once function to Loop 1. Tap Loop 1 when you are finished recording. Your loop is captured, but does not play.

Boomerang III Phrase Sampler Version 2 10/6/2010 Page 17
Hold the Bonus Assign button until the Clock Displays center light blinks green (about 2 seconds). The pedal is in the hopefully familiar Bonus Assign mode, with the center light blinking green. Then tap the yellow Bonus Button. The III enters the Optional Behaviors sub mode and the center light blinks slower. Youll see Octave on green; Once and Stack will be yellow. The other clock lights will be off. The yellow lights represent the two optional behaviors. Turn the green Tap knob (also labeled Vol 3) and the green indicator moves. This is how you select an option to turn on or off. Move the green indicator to select Once. Tap the green Bonus button and the yellow Once light toggles between dim and bright. Dim means the option is off; bright means the option is on. Select Stack and the light will behave the same way, with the same meaning. After making changes, return to normal operation by tapping the Bonus Assign button. The clocks center light stops blinking.

14. Sample Rates

There are 2 sample rates available on your Rang III, 48 and 24KHz. Each rate has a light, and the one thats on shows the current sample rate. The higher rate of 48KHz captures frequencies from 20Hz to over 22KHz. A sample rate of 24KHz captures frequencies from 20Hz to about 12KHz but doubles your available record time. So, the trade off is between loop playback audio quality, and loop record time. The fidelity you require will depend on what youre playing through. Older or traditional tube amps may only reproduce sound from 100Hz 5KHz, while keyboard and acoustic amps cover a much wider frequency range. If you dont run out of loop record time during typical use, just leave your Rang III at the factory setting of 48KHz. You can easily change the sample rate. Hold down the Loop 2 button while powering up and the sample rate will be set to 48KHz. Hold down the Loop 3 button while powering up and the sample rate will be set to 24KHz. Your looper remembers which rate you chose and will power up with the selected sample rate until you change it. See Section 22 for the maximum record time with each sample rate.
NOTE - From the factory, your unit is set to record at 48KHz.
15. Muting the Through Signal
You may have a rig that requires turning off the through signal, the sound of your instrument that passes through the III. This is accomplished by holding down the Assign and Play Style buttons for about 2 seconds. The Thru Mute light turns on bright and your through signal is muted. To restore the through signal, hold down the Assign and Play Style buttons for about 2 seconds. The Thru Mute light turns off.

16. Rear Panel

Input & Output Jacks - smart phone jacks There are two input and two output jacks. The III will function differently depending on which jacks are used. For basic use, plug your instrument into the left input (mono) and connect your amp to the left output (mono). If you plug into both input & both output jacks, your Rang III will record in true stereo. The following table shows all valid connections.
NOTE Make all connections prior to power up.
X = a cable is plugged in.

Power Connector The included power supply plugs in here. The power supply output specs are 9VAC, 9VDC positive tip or 9VDC negative tip, 500-1000mA. Rather open minded wouldnt you say, old boy. The connector should be 5.5mm outside diameter and 2.5mm inside diameter. Pedal Link Connectors - These are not MIDI ports exactly. In software Versions 1 and 2 these connectors serve only one purpose, the In connector is used to upload new software to your Rang III. Expression Pedal Jack Connect your expression pedal here using a stereo cable with tip/ring/sleeve phone plugs on each end. See Section 17 for more juice, Bruce.

17. Expression Pedal

Loop Volume Control Controlling loop volume has always been easy with Boomerang Loopers, and your Rang III is no different. Plug an expression pedal in and you are ready to go. With no additional hassle or setup, the pedal controls the level of your loops when they are playing. Compatible Expression Pedals Purchase an expression pedal that uses a stereo cable (TRS) such as the Korg EXP2, Mission XPB and EP1-R, Roland EV5 & EV7, or BOSS FV-300L, FV-500L & FV-500H. If the pedal does not come with a stereo cable then you will need to purchase one that has a TRS (tip/ring/sleeve) plug on both ends.

NOTE - Expression pedals that use a mono cable (TS) will not work with your Rang III.
Using a Volume Pedal as an Expression Pedal Virtually any passive volume pedal can be used as an expression pedal with your Rang III.
NOTE - An insert cable is required if you are using a volume pedal as an expression pedal.
Insert cables have a TRS plug on one end and 2 mono plugs (or jacks) on the other end. The TRS plug connects to your Rang III and the 2 mono jacks connect to your volume pedal. A few insert cables that should work fine are Hosa STP201RT, Horizon HYS-P , Live Wire TRS(M)-Dual " and Pro Co IPBQ2Q3 or IPBQ2Q5.
NOTE If your volume pedal doesnt work properly, swap the 2 plugs at the volume pedal.

18. Pedal Link System

There are two identical Pedal Link connectors on the rear panel. We hope to add some interesting and useful capabilities in the future if we can. Currently they are only used for downloading software.

19. Clip Light

Input Level Indicator The light to the right of the Boomerang logo indicates input signal level. Its OK if it occasionally turns on, but if it is on most of the time then your input signal is too loud. The pedal will not be harmed but unwanted distortion might occur. If the sound is good to you then dont worry about it. Let your ears make the final decision. Memory Usage Indicator The Clip light also indicates the memorys state. A dim slow blink means there is 10 seconds or less of record time left. A dim fast blink means memory is full and no more recording or stacking can take place until some memory is made available by deleting a loop. If you are recording a loop and memory fills up, recording immediately stops and the loop plays. If your typical usage results in filling the memory frequently, consider trying the 24KHz sample rate.

20. Dos and Donts

25. Downloading Software To the III
** It is highly recommended that you use a PC running Microsoft Windows and not a
MacIntosh. Macs are great but there have been problems downloading software from them. There is the possibility that download errors can render your pedal useless. It wont even power up! Follow the download instructions and use a PC.
** If your pedal doesnt work after a download, you can return it to us and well fix
it at your expense. You will be responsible for all shipping expenses and a $25 fee.
The Overview New software will be sent to you as an email attachment; its a MIDI file. Save it in a convenient directory on your computer. Youll need a USB to MIDI interface. A USB cable connects your computer to your interface device and a MIDI cable goes from the USB/MIDI interface to the Pedal Link In connector on your III. A USB to MIDI cable is a complete interface in one item, and can be purchased for as little as $29. Launch an application that can play MIDI files and set it to output data on MIDI channel 16. Open and play the MIDI file you were sent. You may get a warning saying something like There is no note data in this file. Thats cool as there isnt, only a bunch of SysEx commands. After the file plays, all the clock display lights turn on bright yellow to indicate the new software has been received. Then a second later they all turn bright green to indicate the new software has been permanently saved. Power down the III, move it to your rig and youre set to go. Heres the setup I use: an HP computer running Vista and a program purchased on the net called Sweet MIDI Player 32. My USB/MIDI interface is an M-Audio Fast Track Pro. It works like a charm. The Details Despite the ubiquitous nature of the MIDI interface it is nearly impossible to guarantee the transfer of SysEx data will always be successful for a myriad of reasons. Here though are some suggestions that may help:
NOTE Follow steps 1-6 prior to connecting your MIDI cable to the Rang III.
1) It is highly recommended that you use a Windows-based PC running Windows Media Player (Version 10 or 11) or Sweet MIDI Player 2.4.6 to play the MIDI update file. Be sure the system has had adequate time to boot and no other programs are currently open or running. 2) Open the Control Panel; then open 'Sounds and Audio Devices'. Under the Audio tab check to insure the MIDI Music Playback device is set to your MIDI adapter's MIDI port. If your MIDI adapter has a configuration utility be sure it is set to output SysEx data and is not inserting, merging or generating any other MIDI data, clocks, etc. that might interfere with a proper transfer. 3) Open Windows Media Player and check to see that the 'Repeat' option is NOT checked so the file plays only once. 4) Before connecting the Rang III try opening the MIDI Firmware Update file and playing it to see if it appears to play all the way through without any error messages, pauses, etc. With the BPM (beats per minute) set to 120, the file plays in about 28 seconds. 5) Insure no other programs or devices are running which could also be using the MIDI port and inserting extraneous MIDI data, clocks, etc. This is especially important if you have a complex system with other MIDI-based devices connected. 6) Power-up the Rang III and wait until it is fully booted. 7) Now connect the MIDI cable to the Pedal Link In jack and play the MIDI file once by pressing the Windows Media Player's Play button. The file should play only one time. Once the file has played, the Rang IIIs clock display should light in yellow and then shortly thereafter turn green. This sequence indicates the firmware update has been properly received via the MIDI cable and the update has been stored in the Rang III's permanent memory. Any other result means there has been a corrupted transfer. In this case, please contact us. PROBLEMS Cycle power on the III and try the download again. Cycle power on the III and try using a lower BPM setting, maybe 90 or 100. The lower the BPM, the longer it will take the file to play.
