Replacement Switches
As areplacement for old and new type switch contacts,
amatrix board of new type switches only is available.
Replacement of individual switch is not recommended.
Changing to new type switch contact needs exchanging

CAUTION
When ordering, state the serial number of agiven unit to
allow the factory judge whether revised ROM Ato be

(1) TUNE DATA (1)
Atuning data updated by TUNE button and the alpha TUNE 4^' ^yi: 0^ ^—^'y
dial is stored into the backed up RAM (IC26) on CPU-A
board. The setting is non-volatile, that is, it is retained in —CPU—ASI^CD RAM IC265Cs5'fi:^ TL^
memory even after the unit is turned off.
RiD-IOOO
With Ver. 1.3
On power-up the tuning data is not transferred from the
RAM to CPU-B board which controls voice reproduction
including pitch, resulting in the following phenomena to
appear.
1.The pitch of the Aabove middle Cis 442Hz when the
unit is switched on —regardless of the previous
tuning.
2. Pressing TUNE will display the previous pitch, e.g.
438.0Hz.
3. Rotating the alpha dial will cause the pitch to jump
from 442Hz (on the A) to 438.0Hz +aHz (pro-
portional to the dial turning).

With Ver. 1.4
The RAM-stored tuning data is delivered to the CPU-B
board upon power-up. The modules are ready to sound
at the pitch set before the previous power off —no
descrepancy between the display reading (TUNE pres-
sed) and the actual pitch.
(2) KEYBOARD SWITCH
For more positive contact of the keyboard switch,
change its contact combination as shown in the table
above. Sensitivity to akey touch differs between the
two types. This leads to arevision of ROM Ato change
key touch response of the subsequent stages.
When akey(s) needs replacing, replace agroup(s) of
switches with akeyboard matrix board(s) having the
new type switches.
Exchanging old type switches with the new ones requires
ROM Aof Ver. 2.1 or up.
When ordering, specify whether the existing switches are

to sense the degrees of mechanical reaction force of
the lever. Recall this friction when reassembling the
levers later.
2-2. While holding alever with one hand, remove nut ©
and washer; pull down the lever through the key-
board together with the Tension Rod. Similarly,
remove the other lever.

CIRCUIT DESCRIPTIONS
The CPU on the CPU-A board and the CPU on the CPU-
Bboard transfer data between them in the handshake
format. The program and data flow concerning the both
PCBs are rather complicated and cannot be explained
enough to be understood in alimited space.
Instead, "TROUBLESHOOTING GUIDE" provided on
page 9will aid in determining the basic function of most
vital specific stages.
EQUALIZER
Equalizing stages on the Effect board are represented by
the MID EO. The major difference between MID EQ and
the rest (TREBLE and BASS) being that the latter two
are equipped with afixed-band filter.
MID EQ
BPF (ICs 43, 49, 50 and 51 )is astate-variable bandpass
filter whose parameters are controlled as follows:
Center Frequency ... by MID FREQ from 1C 44
Q... by MID WIDTH from IC46 which turns on or
off Os 39-41
Audio spectrum within the band frequency will be
routed to:
IC55feedback loop via VCA 1C 54b
Next amplification stages via VCA 1C 54a
Since the two VCAs are given control via ICs 53a and b
in opposite direction to each other, the band frequencies
will be either boosted or attenuated depending on
MIDDLE LEVEL setting.
EQ LEVEL
Any audio signal undergoing the EQs would drastically
change its sound energy with various parameter settings
for having the intended tone character or timbre: Even
the same sound source will be reproduced at different
volumes. To compensate for percieved sound volume
difference among voices, VCA IC57 will receive a
control (EQ LEVEL) which is reversely proportional to
the resultant setting of parameters.

1-1 .Set SW1 of the CPU-A board to TEST.
1-2. Press and hold CHORUS, then switch the power on.
1-3. Press VOICE 1. This puts the unit into the checking
mode.
The checking mode falls into two submodes: Mode 1
and Mode 2. The a-dial and the display work in either
submodes much the same way as in the normal edit
mode.
To Enter Mode 1
a. Press FUNCTION and the FUNCTION LED lights.
b. Rotating a-dial will select aparameter one by one in
the order shown in the table below. The value of the
selected parameter will increase or decrease in the
predetermined steps.
NOTE
The waveforms in the table are drawn with akind of
plotter on the paper having uniquely calibrated graticule.
Also, time reference is not given for most of the waves.
Set the scope timebase for appropriate range.
To Enter Mode 2
NOTE: Select this mode after mode 1only when
manually changing the value of aparameter
which was selected in mode 1
.
a. Press EDIT and the EDIT LED will light,
b. Rotating a-dial increments or decrements the value of
aselected parameter.

Notes :
*1 Note numbers outside of the range 15 -113 are transposed
to the nearest octave inside this range.
The Key Transpose operation from the panel does not affect
MIDI IN NOTE numbers
#2 Foot control is regarded as Volume control.
*3 Expression is regarded as Volume control.
#4 If the power has been applied whith the VOICE 1switch
being held down, this message is ignored.
#5 If the power has been applied whith the VOICE 1switch
being held down, this message is ignored.
The program change numbers 64 -127 are ignored.
Even if the Program Change message is recognized, the VOICE
will not be changed to the new VOICE until all on-notes
are turned OFF and Damper is turned OFF.
*6 When the ALL NOTES OFF is recognized, all MIDI-on notes
are turned OFF. However, if the damper pedal is being
pressed, these ON notes will not be turned OFF until the
damper pedal is released. Similarly, if the MIDI Damper ON
message has been received, the notes will not be turned off
until the Damper OFF message is received.
#7 When the power is first applied or when the Basic Receive
Channelis changed by panel operation. Local control will
be set to ON.
#8 These Mode Messages (2nd byte =123 -127) are also
