Discussion about the Korg PolySix synthesizer

Hi,

    In the description of the MG-1 Radio Shack/Moog synth, they discuss the need for 
"high frequency compensation".   This has to do with the fact that in the oscillator, usually they allow a fixed time for discharging the main integrator cap, whereas the charging time varies with frequency.   So at higher frequencies, the discharge time becomes significant and the pitch is too low.   I wonder if the opto-coupler circuit
corrects for this in the P6.

    Bob

I wrote my last reply, sent it, checked my mail and there was your
description of the same circuit, just much better.
