Discussion about the Korg PolySix synthesizer

Hi Kristofer,

Right the resistor you are changing to get your 7 semitones detune is
simply one half of a potential divider. By changing R116, a 220R
resistor, you can alter the bottom half of that divider. By just over
doubling the value to 470R, you will get twice the detune range for ALL
four of the detuned voices.

If you want twice your detune range just alter that one resistor to 470R
and keep using your 1M value. But my reckoning was that if I wanted that
amount of detune I would use the chord hold function on the mode
assigner.

Now what you really need is six sets of pots connected to that unison
circuit. Six 47K linear pots between the power rails, +/- 5V. Feeding a
100K resistor from each wiper to each of the de-mpx inputs in the unison
circuit. This way you would detune either side of perfect note. You
would need some track cuts, but if you can afford the extra panel space
it may be worth it. You could still use my original mod to control the
overall level of detune.
