UNIVERSAL PARAMETER
UNIVERSAL
PARAMETER
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
MANUAL
DATA DUMP
The upper readout will shown MD. Now use bank B pro-
gram 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 KX88’s 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.

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 every-
thing 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,
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.
