Discussion about the Korg PolySix synthesizer

I've managed to improve the scaling a bit.

Before:

0.018
0.042
0.090
0.185
0.375
0.755
1.513
3.03x

After:

0.023
0.045
0.090
0.182
0.366
0.740
1.490
2.98x

VR1 has the least effect; that's the one that has the tuning "drift back" a
bit after adjusting it. But it doesn't go back completely.

Admittedly VR2 is now in its extreme position. There probably is still room
for improvement. It would be nice to have a definite table for all this.

I've done all the measuring with the "Tune" knob in the middle and the
pitch wheel centered. This voltage is also part of the calibration;so if
you have the tuning knob in a different position you'll end up with
different values.
