KEY CODER &KEY ASSIGNER LSI (YM26600) DA CONVERTER LSI (YM26700)
The LSI detects what keys are held down by judging the
pulse combination of the octave and note.
It also generates the seven bit key code, which is processed
by time sharing, in accordance with the key held down.

Pitch Adjustment
"Before earring out pitch adjustment, be sure to stabilize electrical circuits of your synthesizer more than 10 minutes after power switch
is turned on.
1. Adjust the following variable resistors, when tuning knob on the panel is in the center position, so that the voltage of TU terminal
is +4V ±0.1% between the terminals TU (67) and Eon KAS circuit board.

*Make sure, all the levers on the panel are in "OFF" position.
Short circuit terminals EK (19) and E(1)(2) on Mcircuit board when tone selector is set to "FLUTE" and transposition lever is
in OCT-UP (2' on CS-80) (+15V, terminal VIII on Mcircuit board) position. Then, adjust VR1 (B-10K) on Mcircuit board so that
the voltage of terminal Cp (5) is within 0V ±120/jV.
With checking the output frequency from the 9th pin of IC9 (WSC) on Mcircuit board, adjust the VR3 (B-5K) to have the certain
highest note.
CS-50, 60 C7 to be 4186 Hz +1cent when C6 key is depressed.
CS-80 C8 to be 8372 Hz ±1cent when C6 key is depressed.
In the same manner, set the lowest note by adjusting the VR2 (B-500) as follows.
CS-50 C3 to be 261 .6Hz ±1cent when C2 key is depressed.
CS-60 C2 to be 130.8Hz ±1cent when C1 key is depressed.
CS-80 C3 to be 261.6Hz ±1cent when C1 key is depressed.
Note:
(1 )You can easily find out which Mcircuit board is corresponding to the key depressed by hearing the subtle change of the
tone with hum modulation when you are adjusting VR2 on AMcircuit board.
(2) The order the possible sounds when keys are depressed in turn is:
©+©+©+©* ©+©*® *©
When keys are depressed at a time:
©+©*©*©*©>© +©+©*©
Therefore, when you adjust the M8 circuit board, depress the 8th key while 7th key is holding down, then release the 7th
key. In this way, you can take out the sound of 8th key depressed.
Adjust the following variable resisters, when transposition lever is in "NORMAL" ("4'" on CS-80) position (+15V at terminal
IV) as below.
CS-50, 60 VR4 (B-1K);C6 to be 2093Hz ±1cent when C6 key is depressed.
CS-80 VR4 (B-500): C7 to be 4186Hz ±1cent when C6 key is depressed.
Adjust the following variable resistors, when transposition lever is in "1 OCT-DOWN" ("8"' on CS-80) position (+15V at terminal
II) as below.
CS-50, 60 VR5 (B-2K);05 to be 1046Hz ±1cent when C6 key is depressed.
CS-80 VR5 (B-1 K); C6 to be 2093Hz ±1cent when C6 key is depressed.
Likewise, adjust the followings, when transposition lever is in "2 OCT-DOWN" ("16' "on CS-80) position (+15V at terminal I)
as below.
CS-50, 60 VR6 (B-5K); C4 to be 523.2Hz ±1cent when C6 key is depressed.
CS-80 VR6 (B-2K);C5 to be 1046.4Hz ±1 cent when C6 key is depressed.
Finally, adjust the generating circuit for tuning standard voltage, when A3 key is depressed, so that the output is 443 Hz.
