MS-20 question

[punkdISCO]

Good find Micke.  Yes, it looks like FM is the solution..

Makes me want one even more:(

Yes, the new MS20m has dropped the VCO 2 CV In (just under the volume knob):

At first I thought it was a bit stupid as the sync effect is mostly interesting when modulating the pitch of VCO2 but there seemed to be no way for this to be modulated separately (except manually) but I might have found another way…


Here’s the section on the new features from the manual:


1. SYNC VCO 1->2 ON/OFF switch
This switch turns on/off syncing of VCO 2 with the VCO 1 frequency. 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 FREQUENCY MODULATION is automatically set to the FM INTENSITY 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 (REV1) and the later filter (REV2).


4. VCO 1 PWM IN jack
When the triangular wave output of the MODULATION GENERATOR (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 motions.


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 voltage 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. According 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 simultaneously.


10. JUNCTION jacks (3 lines)
One mini-phone jack and three standard phone jacks are connected 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.




I can probably apply modulation to VCO2 pitch separately with SYNC on if I also set FM on but with an intensity of 0.
