MS-20M Parts and Their Functions
MS-20M parts that are different from the original MS-20 are described below. Refer to the original Owner's Manual for details on parts
that are the same as on the MS-20.

1. SYNC VCO 1→2 ON/OFF switch
This switch turns on/off syncing of VCO 2 with the VCO 1 fre-
quency. The sync effect is easier to hear when PITCH of VCO 2
is set higher than PITCH of VCO 1.
2. FM VCO 1→2 ON/OFF switch
This switch turns on/off frequency modulation of the VCO 2
waveform with the waveform output of VCO 1.
When this switch is set to ON, the MG/T.EXT level of FRE-
QUENCY MODULATION is automatically set to the FM INTEN-
SITY level. In addition, the connection at the TOTAL jack is cut,
and the EG1/EXT level only affects VCO 2; it does not affect
VCO 1.
3. FILTER TYPE REV.1/REV.2 switch
This switch selects between the earlier filter (REV.1) and the
later filter (REV.2).
4. VCO 1 PWM IN jack
When the triangular wave output of the MODULATION GEN-
ERATOR (LFO) is patched to this jack, PWM will be applied to
the square wave of VCO 1. At that time, the PW level becomes
the INTENSITY of PWM.
5. EG 2 NORMAL OUT jack
This is the normal EG 2 output jack that changes from 0V to
+5V.
If this output is patched to the CUTOFF FREQ jack of VOLTAGE
CONTROLLED HP FILTER or LP FILTER, the SUSTAIN LEVEL
knob of ENVELOPE GENERATOR 2 can create general mo-
tions.

6. TRIG IN (0V → High) jack
This is a standard specification trigger input jack typically used
by products from manufacturers other than Korg or Yamaha.
According to this standard, the trigger is applied when the volt-
age is increased from 0 V to a + voltage.
7. VCO 1+2 CV IN (V/Oct) jack
This is a standard specification CV input jack typically used by
products from manufacturers other than Korg or Yamaha. Ac-
cording to this standard, the pitch increases by 1 octave with
each 1 V that the CV voltage is increased.
8. TRIG SW OUT jack
This is an output jack that drops to GND when the TRIG SW
button (push-button), described below, is pressed. This is the
same as the MOMENTARY SWITCH jack on the original MS-
20.
9. TRIG SW button
Pressing this button performs the same operation as pressing
C3 in the keyboard. The C3 pitch and trigger on are applied si-
multaneously.
10. JUNCTION jacks (3 lines)
One mini-phone jack and three standard phone jacks are con-
nected in parallel. These provide three lines. They can be used
to split a single output signal between multiple input jacks or to
convert a mini-phone plug to a standard plug.
