Discussion about the Korg PolySix synthesizer

OK then, so what is the voltage reading on the left-hand base of T3 with the
MG frequency pot at 0 and at 10? Also what is the emitter voltage at with
VR5 fully clockwise/counter clockwise? The tricky part is that the frequency
is determined by the current input at IC21 pin 16, which isn¹t so easy to
measure. But the voltages into the circuit might give us some clues...

Cheers,
A
