Discussion about the Korg PolySix synthesizer

Hi

Due to tuning problems I have replaced PC1 with a vtl5c3 and R93 with a
1K2 resistor on my PolySix.
However my it still appears to have some tuning and filter? issues.

I have uploaded a mp3 which "shows" the problem(s):
/Files/Misc/P6Test.mp3

First 6 notes
Cutoff: 10
Res: 0

Last 6 notes
Cutoff: 6
Res: 7

sounds like the voices are at different volume, tune (and maybe
res+cutoff?). Especially voice 0 and 2 seem to be different than the
others.


Also When tuning eg. A4 key, the other octaves are totally out of tune.

Is it possible to adjust the voices without a oscilloscope?

Thanks in advance,
Hjulskov
