FEATURES

1. KEYBOARD An 88 key weighted action keyboard with initial and after touch sensitivity. It functions in three modes; SINGLE, DUAL and SPLIT. 2. WHEEL 1 3. WHEEL 2 Wheel 1 is a center-return pitch-bend type, and Wheel 2 is a modulation wheel type. These wheels perform the functions assigned to them. 4. CSI-4 Continuous Sliders 1-4 perform the functions assigned to them. 5. TS1,2 Toggle Switches 1 and 2 each perform 2 functions, one when the LED is on, and one when off. Each time TS1 or 2 is pressed, the LED alternates on/off, and it will perform the function assigned to it. 6. MS1-5 Momentary Switches 1-5 perform the function assigned to them each time they are pressed.
7. MODE SWITCH This switch selects between the 3 operation modes. Each time the MODE switch is pressed, it will alternate between PLAY and CA mode. While in CA mode, if you press MODE for more than 1 second, it will enter PA mode. 8. MODE INDICATOR LED In PLAY mode, it indicates one of the three keyboard modes; SINGLE, DUAL or SPLIT. 9. ASSIGN LED In CA mode, the upper LED (CONTROLLER) will be lit, and in PA mode, the lower LED (PARAMETER) will be lit. 10. UPPER READOUT, LOWER READOUT In PLAY mode, this displays the voice program number 1-32 for bank A. (In 8 BANK mode, 1-128) When CA mode is first entered, CA will be displayed. Depending on the function, it will display the selected controller, MIDI channel or transpose point. When PA mode is first entered, it will display PA. In PA mode, depending on the function, it will display data. In PLAY mode, it will display the voice program number for bank B. In CA mode, it will display the controller code, MIDI channel or transpose point. In PA mode, it will display data.
11. BANK SWITCH A, B These are used to chose whether the program select switches select 1-16 or 17-32. (Or in 8 BANK mode, to select banks 1-8) When the bank LED is off, the program select switches select 1-16; when on, 17-32. In CA mode, they enable or disable assignments to each bank. 12. BANK A PROGRAM SELECT SWITCHES In PLAY mode, these select the voice program number of the MIDI tone generator units connected to the KX88. In 2 Bank mode, 1-32. In 8 Bank mode, 7-128. In CA mode, they perform the functions printed above the switches, and in PA mode, the functions printed below the switches. 13. BANK B PROGRAM SELECT SWITCHES In PLAY mode, these select voice program numbers just like the Bank A Program Select Switches: In CA mode, they are used to assign controller codes to controllers. In PA mode, they are used to enter data.
14. CONTROLLER CODE PRESET TABLE The functions for controller codes 00-3F have been permanently set, and are listed here. 15. MIDI IN, OUT JACKS Connect a MIDI tone generator to the OUT jack, and a remote keyboard such as the KX5 to the IN jack. 16. FOOTSWITCH JACKS Connect footswitches (such as the FC4 or FC5) to this jack. They will perform the function assigned to them. 17. FOOT CONTROLLER JACKS Connect foot controllers (FC7) to this jack. They will perform the functions assigned to them. 18. BREATH CONTROLLER JACK Connect a Yamaha BC1 to this jack. It will perform the function assigned to it. 19. POWER SWITCH This turns the power on or off.

PORTAMENTO ON/OFF, PORTAMENTO TIME, LFO SPEED Now press the other toggle switch, TS2. (TS2 = Portamento ON, Portamento OFF) When the TS2 LED is on, portamento will apply to the keyboard. (Again, all these settings can be applied to MIDI channels A and/or B, as we will explain later on p. 14) If the portamento time is too short, you will not be able to hear it. So, adjust the portamento time. CS4 (continuous slider) has been assigned to portamento time. (CS4 = portamento time) Move it up and down to adjust the portamento time. CS3 = LFO speed. Move it up and down to change the LFO speed. NOTE: LFO speed is a voice parameter, and the KX88 is sending System Exclusive messages (Yamaha ID number) to change them. If you are using other companies tone generator units, you will have to change these parameters by assigning a Universal Parameter. (see page 20.) CS1 and CS2 have been assigned to VOLUME for banks A and B. Move them and notice how the volume of each tone generator changes.
If you press MS2, you will return to DUAL mode. (MS2 has been preset to DUAL, ie. MS2 = DUAL) When you play the keyboard, both tone generators will sound, since both MlDI banks are active. There is one more keyboard mode, SPLIT. Press MS3. (MS3 = SPLIT) The LED will indicate SPLIT. In SPLIT mode, notes played on or below the split point will be sent on MIDI bank A, and notes played above the split point will be sent on MIDI bank B. If you press MS3 again while you are in SPLIT mode, the upper readout will show SP and the lower readout will show the current split point. C3 Touch the keyboard where you want the new split point to be, and the new split point will be displayed. A decimal point indicates a sharp. (#) SWAP Press MS4. (MS4 = SWAP) This will interchange MIDI banks A and B. Notice that the voice program numbers in the readout have traded places. Now, MIDI bank A is channel 2, and B is channel 1. If you SWAP while in SPLIT mode, the sound that you were playing on the lower part of the keyboard will interchange with the sound you were playing in the upper part. MIDI CHANNEL Press MS5. (MS5 = MIDI CH) The readouts will show the MIDI channel number for banks A and B. (Later, we will learn how to change the channels.)
Lets try the other controllers. WI = Pitch Bender, W2 = Mod Wheel, After Touch = After Touch, Breath Controller = Breath Controller, FC1 = Volume, FC2 = Foot Controller, FS1 = Sustain switch, and FS2 = Portamento switch. All of these will affect the MIDI tone generator or synthesizer in the normal way. For example, if the DX7 function memory is set so that Foot Controller Range is 99 and Foot Pitch is ON, then using the FC2 connected to the KX88 will change the Pitch Modulation of the DX7.

TS1,2 These switches each have two functions, so you must assign two controller codes to them. In PLAY mode, if TS is pressed while the LED is off, the first function will be sent. If it is pressed when the LED is on, the second function will be sent. When you press TS1 or 2 in CA mode, the upper readout will show T1 for about one second. Then, the upper and lower readouts will show the first and second controller codes currently assigned to that switch. Enter the new controller codes using bank B program select switches 1-16. (0-F) MS1-5, FS1, 2 Select these controllers by pressing the controller itself. The upper readout will indicate the selected controller. Enter the new controller code using the bank B program select switches.

SAVE SAVE

All the settings and assignments made in CA mode may be stored in one of 16 code memories. Use bank B program select switches 1-16 to choose the code memory you want to save the current settings in. The selected number will blink in the lower readout, and when you press that same number again, all current settings will be stored in that code memory as follows. All controller code assignments and bank A/B enable/disabble settings made in CA mode. Transpose points A and B Bank select 2/8 Split point Bank A and B channel numbers

LOAD LOAD

MIDI CH
Use this to recall the setting you saved in 7. When you press this switch, the upper readout will show L0. Use bank B program select switches to select the desired code memory.
The MIDI channels of banks A and B will be displayed. Select the bank you want to change by pressing bank switch A or B, and select the new channel with bank B program select switches 1-16. TRANSPOSE

TRANSPOSE

INTERNAL FUNCTIONS Controller codes 00-3F have been preset with various functions. When in PLAY mode you operate a controller that has been assigned one of these controller codes, this is what happens. 00 SINGLE The keyboard mode changes to SINGLE, and sends key on/off information on either bank A or B.
You may transpose banks A and B independently. The current transpose point for banks A and B will be shown in the readouts. Select the bank you want to transpose by pressing bank switch A or B, and press a key at the desired transpose point. (A decimal point indicates a #.)
01 DUAL The keyboard mode changes to DUAL, and sends key on/off information on both banks A and B. 02 SPLIT/SPLIT POINT The keyboard mode changes to SPLIT, and sends key on/off information from the lower part of the keyboard on bank A, and the upper part on bank B. If this is activated While Already In Split Mode, the upper readout will display SP, and the lower will display the current split point. The next key you touch will be the new split point. If you do not want to change the split point, press MODE. 03 SWAP CHANNEL This interchanges the MIDI channel numbers of banks A and B. The voice program numbers in the readouts will change places.

Use this to define controller codes 40-FF as SYSTEM EXCLUSIVE: PARAMETER CHANGE messages. When you press this switch, the upper readout will show PC. Enter the controller code you want to define. The upper readout will shown LM (Limit) and the lower readout will shown OF (Off). This allows you to select an upper limit for the data of the parameter change. Use the bank B program select switches 1-6 to select an upper limit of 3, 7, 15, 31, 63 or 99. If you press bank B switches 7-16, the limit will be off. (127 max)
After you have specified the limit, the upper readout will show G. Enter the group number (00-1F) of the parameter you want to change. Next, the upper readout will show SG, so enter the subgroup (0-3). Next, the upper readout will show P, so enter the parameter number (00-FF). NOTE: System Exclusive messages include an ID number which is different for each manufacturer. Controller codes you define using PARAMETER CHANGE will affect only Yamaha equipment. To define System Exclusive messages for other manufacturers products, use the Universal Parameter function.

UNIVERSAL PARAMETER

SPECIAL FUNCTIONS
MIDI STATUS AND ACTIVE CLOCK disable The KX88 normally sends MIDI status and active clock signals, but you may disable this by turning the power on while pressing the MODE switch. MEMORY INITIALIZE By Turning on the power while pressing bank switches A and B, you can set all code memories to the initial setting on page 32. (Obviously, this wipes out everything you have set.) The readouts will display 0 for both A and B. When the memory backup battery runs low, the readout will display for about 0.5 seconds when you turn the power on. If this happens, contact your Yamaha dealer. ERROR MESSAGES When an error occurs, the upper readout will show Er, and the lower will show the following codes. Error 1. Serial input overrun, framing error. Error 2. MIDI input buffer overflow. Error 3. The MIDI active sensing clock was interrupted for more than 300 m sec. MIDI INPUT The KX88 sends out exactly what comes in to the MIDI input. (echo back) You may think of it as a MIDI mixer. The KX88 will not process incoming MIDI data,
Using this, you may define controller codes 3E and 3F as any MIDI message of up to 8 bytes. The controller data (00-7F) will be included in this message in whatever spot you specify. When you press this switch, the upper readout will show UP. Now choose Universal 1 or 2 (controller code 3E or 3F) by pressing bank B program select switches 1 or 2. The readout will show b1, prompting you to enter the first byte. As you enter each byte, the upper display will show which byte you are now entering. At the place you want the controller data to fit in, press bank B switch, and the lower display will show dA. (data) When you finish, press PARAMETER CHANGE switch again.

MANUAL DATA DUMP

The upper readout will shown MD. Now use bank B program select switches 0-F to enter up to 20 bytes of MIDI information. The last byte you entered will be displayed in the upper readout. When you have finished, press MANUAL DUMP again, and the string of data you inputted will be sent. NOTE: This data will not be stored in the KX88s memory. It is sent and forgotten. CHECKING CONTROLLER CODES If while in PA mode, you enter a controller code number (using bank B program select switches), the data for that controller code will be displayed for about 1 second, as follows.

PRECAUTIONS WHEN USING THE KX88 WITH THE DX7
For the DX7 to accept parameter change messages, it must be set to SYS INFO AVAIL. When you change a function (for example portamento time) from the KX88, the portamento time of the DX7 will change, but the DX7 display will not indicate this. While you are modifying a DX voice parameter, the sound will be interrupted. This is the same whether you do this from the DX or from the KX. When you use Parameter Change, make sure the data limit is correct for that particular parameter.
CHAPTER 3: SETTlNG UP THE KX88
CA (controller assign) MODE
In the last chapter, we learned what functions had been assigned to the controllers when the KX88 left the factory. In this chapter, we will learn how to assign any function to any controller. Most of the frequently-used functions have been stored in the KX88s memory and given a number; a CONTROLLER CODE. (These CONTROLLER CODES) are printed on the right side of the KX88. The steps in assigning a controller are 1. Select a controller. (bank A switches 1-10, TS, MS and FS switches) 2. Enter the controller code. (bank B switches 0-F) To say it another way, you must decide 1. Which controller? 2. Does what?

Wheel 2 = Volume

Lets try assigning Wheel 2 (W2) to Volume. (W2 = Volume) Enter C.A. mode by pressing the MODE switch. The LED will indicate CONTROLLER and the readout will show CA.

Readout display codes

Now, we must choose which controller we are assigning; in this case W2. Above the bank A program selector switches 1-10 you will see the various controllers indicated. Select Wheel 2 by pressing program selector switch 2. The upper readout will show which controller you have selected.
T1 TOGGLE SWITCH 1 M 1 MOMENTARY SWITCH 1 W1 WHEEL 1
BREATH CONTROLLER AC AFTER TOUCH CONTROLLER C1 CONTINUOUS SLIDER 1 F1 FOOT CONTROLLER 1
FOOT SWITCH 1 PARAMETER ASSIGN SAVE SPLIT POINT SONG SELECT PARAMETER CHANGE
Now, using the bank B program select switches 1-F, enter the CONTROLLER CODE you want to assign to Wheel 2. In this case, volume, which is controller code 17. Press bank B program select switch 1 and then 7. NOTE: In CA mode, the numbers of the select switches go from 0 to F, as is written above the switches.

If you want to change MIDI channels A or B, press bank switch A or B and the selected readout will start blinking. Enter the new MIDI channel by pressing one of the bank B program switches 1-16. The new channel number will be displayed.
To get out of this function press MIDI CH again.
This lets you switch between 2 BANK and 8 BANK mode. Each time you press the BANK 2/8 switch, the upper readout will display BN (bank number) and the lower readout will alternate between 2 and 8.
This function may be selected while in PLAY mode by assigning a controller to controller code 04.
TRANSPOSE To leave this function, press any other switch. The Yamaha DX and TX voice program memories are 1-32. However, some MIDI synthesizers may have up to 128 voice program memories. To select voice programs 1-128, set it in 8 BANK mode. For the details of selecting voice programs in 8 BANK mode, see page 26.
The KX88s keyboard may be transposed up or down in half-steps, to a maximum of +2 octaves. When you press this switch, the readouts will display the current transpose points for MIDI banks A and B.
As originally set up, the transpose point will be C3 for both banks, meaning that pressing C3 on the keyboard will send a C3 key on signal to both channels. (i.e. normal position) If you want to change the transpose point, press bank switch A or B to choose which bank you are transposing. The selected bank readout will start blinking.
The KX88 has 16 CODE MEMORIES. Everything you assign or set in CA mode can be stored in one of these memories. When you press SAVE, the upper readout will display SA. Use the bank B select switches 1-16 to choose which code memory you are going to store the current settings in. The selected number will blink in the lower display, allowing you to double check. If that is the code memory that you want to use, press that same number again, and all the current settings will be saved in that code memory. Naturally, the previous setting will be erased.
Lets save the assignments you have made so far (if you have been following the examples) in code memory 2. Press SAVE and then press bank B program switch 2.
PA (Parameter Assign) MODE In the last section (CA mode), we learned how to assign controller codes to controllers. Controller codes 00-3F and their definitions are printed on the KX88. These controller codes cannot be redefined. However, you may define the remaining controller codes 40-FF to be any MIDI information you want. The basic procedure in PA mode is; 1. Enter a controller code (40:FF) 2. Enter MIDI data for that controller code.
FUTURE USES OF PA MODE There are still some undefined messages in MIDI. This is because musical instrument manufacturers have agreed to leave room for future developments. When this happens, you will use PA mode to define controller codes as these new MlDI messages. Depending on what type of MIDI data you want to send, there are 3 main functions in PA mode. (bank A select switches 11-13)

Controller code 41 = Op. 6 Frequency Fine
As an example, lets try changing the Op. 6 Frequency Fine of the DX7 (or TX). Press bank A switch 11 (CONTROL CHANGE). The upper readout will show CC. Enter PA mode from CA mode (if you are not already in), by pressing MODE for about 1 second. The upper readout will show PA.
Enter the controller code that you want to define (in this example, 40), using the bank B switches 0-F. Press bank A switch 12. (PARAMETER CHANGE) The upper readout will show PC.
Enter the MIDI control number you want. (in this example, 01)
Enter the controller code you want to define, using the bank B switches O-F. In this case, lets define controller code 41.
Enter the DATA TYPE. (0, 1 or 2) This will only apply to Foot Switches 1 and 2. (for details, see page 00.) For now, just enter 0.
The upper readout shows LM (Limit). This is where you set an upper limit to the data number. If you check the DX, you will find that the Op. 6 Frequency Fine has a range of 0 to 99. So, choose a limit of 99 by pressing bank B switch 6. (For details why, see page 00)
Go to CA mode and assign controller code 40 to a controller, for instance CS3. Then, go to PLAY mode an try out CS1. It will perform the same function as the Modulation Wheel. In reality, of course, it would have been much simpler just to assign controller code 11 (which is already preset as Modulation Wheel), without bothering with PA mode. The above example is for your future reference.
Now the upper readout will show G. (Group) Look in the DX7 MIDI data list and find the group number for the parameter you want. In this case it is 00, so enter 00.
Next, the upper readout will show SG (Subgroup). Enter the appropriate subgroup. For this example, 0.
Controller Code 43 = Op. 6 Keyboard Level Scaling Break Point The idea of this assignment is to use a Foot Controller to move the break point up and down the keyboard. If the left and right level scaling depth is set rather high (-LIN), and if this operator is a modulator, you will get a very strange Wah effect swept up and down the keyboard. Anyway, lets give it a try. Enter PA mode. Press PARAMETER CHANGE. Enter the controller code. (43) Assign the limit. Keyboard Level Scaling Break Point has a range of 0 to 99. So press bank B switch 6 to set a limit of 99. Enter the group number. (00) Enter the subgroup number. (0) Enter the parameter number. (Op. 6 Keyboard Level Scaling Break Point is 08) Go back to CA mode and assign controller code 43 to FC2. Then, go to PLAY mode and try it out. The effect will change depending on the voice, especially Op. 6 output level and level scaling settings. Experiment with it.

Now the upper readout will show P (Parameter), so enter the parameter number. The parameter number for Op. 6 Frequency Fine is 13 (Hexdecimal).
Now go back to CA mode and assign Controller Code 41 to a controller, for example CS3. Then, go to PLAY mode and try out the new assignment you have made. As you move the slider, the harmonic structure of the sound should change interestingly.
Controller Code 42 = Feedback Controlling the amount of feedback (in a DX synthesizer operator) using Aftertouch is also interesting. Enter PA mode. Press PARAMETER CHANGE. Enter the controller code you want to define. (42) Assign the limit. The DX series feedback has a range of 0 to 7. So, press bank B switch 2 to select a limit of 7. (For details, see page 28) Now enter the group. number for the parameter you want. (See the DX7 MIDI data list on page 00) In this case, 00. Enter the subgroup. In this case, 0. Enter the parameter number. In this case, 07. Go back to CA mode and assign controller code 42 to Aftertouch. Then, go to PLAY mode and try it out. Try using a voice that normally does not have very much feedback. When you press down on the keyboard, the sound will become much brighter.
Controller Code 44 = PITCH EG Level 1 Heres another interesting setting. Its especially effective if you enable it for only one MIDI bank. Enter PA mode. Press PARAMETER CHANGE. Enter the controller code. (44) Set the limit. PITCH EG Level 1 has a range of 0 to 99, so press bank B switch 6 to choose a limit of 99. Enter the group number. (00) Enter the subgroup number. (1) Enter the parameter number. (Pitch EG Level 1 is 02) Go back to CA mode and assign controller code 44 to CS3. (Disable bank B) Then, go to PLAY mode and try it out. It will help if you set Pitch EG Rate 2 to a moderate rate (about 20) When you hit a note, the two tone generators will at first be dissonant, and then slowly resolve. Use CS3 to adjust the amount of effect. (In center position, no effect.) By now you should have a fairly good idea of the possibilities of the KX88. It is important to keep a record of the settings you have made, and we suggest that you copy and use the form on page 00. If you have been following all the examples, the form would look like this.
OTHER PA MODE FUNCTIONS PA mode has two other useful functions. MANUAL DUMP
If you want to define a controller code as a SYSTEM EXCLUSIVE for a device other than Yamaha, or if you want to send any MIDI data other than Control Change or Parameter Change, use this function. Universal 1 and Universal 2. (see Controller Code Preset Table) In PA mode, you may use UNIVERSAL PARAMETER to define these as a MIDI message of up to 8 bytes, and include controller data in this message.

1. Once $FE has been received, if data or status signals are not received within 300+10 msec, an error will be assumed, The display will indicate error, and transmission and reception will stop. 2. For output STATUS BYTES will be abbreviated. (running status) 3. When a STATUS BYTE with an incorrect number of DATA BYTES has been received, neither that STATUS nor DATA byte will be echoed back. 4. A string of up to 20 bytes of user-specified data may be sent using MANUAL DUMP. 5. Using UNIVERSAL PARAMETER, controller data may be transmitted inside a user-specified string of up to 8 bytes. 6. By a special function when turning the power on, you may cancel the abbreviation of STATUS BYTES. (running status)

FCC CERTIFICATION (USA)
While the following statements are provided to comply with FCC Regulations in the United States, the corrective measures listed below are applicable worldwide. This series of Yamaha combo equipments use frequencies that appear in the radio frequency range and if installed in the immediate proximity of some types of audio or video devices (within three meters), interference may occur. This series of Yamaha combo equipments have been type tested and found to comply with the specifications set for a class B computing device in accordance with those specifications listed in subpart J of part 15 of the FCC rules. These rules are designed to provide a reasonable measure of protection against such interference. However, this does not guarantee that interference will not occur. If your combo equipment should be suspected of causing interference with other electronic devices, verification can be made by turning your combo equipment off and on. If the interference continues when your equipment is off, the equipment is not the source of interference. If your equipment does appear to be the source of the interference, you should try to correct the situation by using one or more of the following measures: Relocate either the equipment or the electronic device that is being affected by the interference. Utilize power outlets for the combo equipment and the device being affected that are on different branch (circuit breaker or fuse) circuits, or install AC line filters. In the case of radio or TV interference, relocate the antenna or, if the antenna lead-in is 300 ohm ribbon lead, change the lead-in to co-axial type cable. If these corrective measures do not produce satisfactory results, please contact your franchised Yamaha combo equipment dealer for suggestions and/or corrective measures. If you cannot locate a franchised Yamaha combo equipment dealer in your general area contact the Combo Service Department, Yamaha International, 6600 Orangethrope Ave., Buena Park, CA 90620, U.S.A. If your any reason, you should need additional information relating to radio or TV interference, you may find a booklet prepared by the Federal Communications Commission helpful: How to Identify and Resolve Radio -- TV Interference Problems". This booklet is available from the U.S. Government Printing Office, Washington D.C. 20402--Stock No. 004-000-00345-4.
