Korg PS 3200 - 9. Modulation Generator-1 (MG-1)

The MG-1 is basically an LFO.
 It's quite central to modulation in the Korg PS 3200.
The voltages it produces is used for FM (frequency modulation) , FcM (cutoff frequency modulation) and AM (amplitude modulation) within the synth.

4 WAVEFORMS + pink & white noise.
The input on the left controls the frequency of the MG1
-5V to +5V

The MG is hardwired to the Signal Generators (SGs), the Filters & the VCA (Modulation Balance) sections.
That is, you don't need any patch cables to modulate these components.

When switched to the SGs you get FM.
When switched to the filters, you get cutoff frequency modulation (FcM)... called "Growl".
When switched to the Modulation Balance (VCA) section you get AM.... tremelo or ring modulation.

Looks like a good patch to try

 The PS 3010 is useful but a synth such as a MS 20 should also produce interesting results.
