Korg PS 3200 - 2. Signal Generators

There are 2 SGs per voice

The top 4 knobs are pretty standard waveform & octave selectors
The fine tune knob  adjusts only SG2.

Speed & intensity are all about PWM .
Speed adjusts the frequency of the signal modulating the pulse width.
Intensity  controls the sensitivity of modulation.

The pulse width of SG 1 & SG2 can be modulated by either MG-1 or the Sample & Hold

The MG-1 or S/H  knob adjusts the sensitivity to modulation by the MG1 or the S/H,

Notice the two red switches on the bottom of this pic.
The one on the left, marked reverse, .... it reverses the phase of any external modulation signals.
The right switch, turns FM (from any external sources) on or off.

 These lower switches, the two knobs & 6 jacks are for external modulation sources.
Not MG-1 or the S/H. More about this later.
