Doepfer

Thanks that sort of answers the question.
Although I still face the massive task of tuning the oscillators.. ;-(
Do any of you here have some good tips on how to do that?
Both my effort were a bit frustrating.
The description op the Doepfer site is a wee bit minimal to my taste.
What I'm looking for is where to start and what to watch.

Thanks..

Ernst
