Doepfer

Thanks Ingo..

Although I was more after a method.
Where to start.. what to look for.
Spread, fine tuning.. etc..
I've come a long way now.
Using my ears a lot.

Nevermind. I got the broken a111 tuned now.
I defiantely know that both a111's are the old type.
Also: suddenly bakis' magic "patchcord in the Hard Sync input- method"
does not work anymore...
Broken socket indeed...
I will have to order some parts from doepfer then...

Thanks & greetings,

Ernst
