Re: [korg_mono-poly] VCO 2 trouble

2010-07-15 by Florian Anwander

Hi Jeppe


I am not sure, whether I answered you personally or not. So once again 
to the list: This should be a faulty IC7 on the VCO board. Originally a 
HD14066BP, but you can take a CD4066B (or even a CD4016B which is pin 
compatible) without any problem.
If you replace this chip, it might(!) be possible that you have to 
readjust the V/Octave setting

And in Poly mode it's quite annoying (even thoughs it is a cool effect with one oscillator sliding after the other in a sloppy fashion when doing chords).
