Korg PS 3200 - 7. Modulation Balance / Modulation VCA

There is just one knob & one input jack, but this section is very important, as it controls the balance between the modulation signals coming from the MG-1 and the S/H.

The balance between the MG-1 & S/H can be controlled manually  with the knob.
However, it can also be controlled with CVs via the VCA control input jack.
Attack requires a CV between -5V and + 5V.

Release uses a S-trigger (5V)

...

The MG-1 & S/H CVs are used alot in the PS 3200...such as applying FM to the signal generators.
MG-1 is used for effects like vibrato, and auto wow.
The S/H  uses the MG-1 signal as the clock, and produces a stepped output CV for things such as random notes, and random cut-off frequency.

A trigger from the keyboard sets of the GEG (more about this patch later).
