VCO 2 trouble

VCO 2 trouble

2010-07-12 by suicidesushi82

Hello everyone.

So, I bought my MP almost a year ago, which resulted in me selling all the other synths I had laying around - they all faded in comparison. It sounds so fraking good! 

One problem though. My VCO 2 wont stop "portamentoing" before the MP has been turned on for more then an hour. This means I often have to play it with VCO 2 turned alle the way down. 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).

When i turn the portamento button all the way down VCO 2 acts like portamento is turned all the way up. When i turn the portamento button up a notch VCO 2 acts like the other VCO's.

Do you have any experience with this problem?

Oh, and is it possible to repair the microcontroller buttons on the MP? My "hold" buttons is very bad at senseing when i press it.

Thanks a lot.
Jeppe

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
