DUSG tracking

DUSG tracking

2011-11-23 by Mongo

Hi,

I've recently built my first DUSG module, and the only thing I'm having problems with right now is the '1V/Oct' tracking. I'm not expecting this to be as good as a normal VCO, but I'm finding that I'm not able to get this close enough to even track a single octave.

If I want to improve this, would it help to put a trimmer in the voltage divider on the 'E' pin? Or is there some other way to address it.

BTW - I posted a little review thread over on electro-music if anyone's interested.

thanks
Gary

Hi folks -

I have been pointed to a thread on muff-wiggler that addresses this issue. The answer is to replace the 1k8 with a 1K fixed plus a 2K trimmer.

Thanks Stephen!
