Re: [Doepfer_a100] Tuning references for A156 quantizer

2016-08-19 by Nicholas Keller

I hadn't thought to check the 156 for adjustment. I've been struggling with tuning for some time now and almost always have a 156 in the patch. Thanks for bringing this to my attention. I'll check the scale of my 155 while I'm at it!

Funny thing, I am more collecting and adjusting my Doepfer setup (or Dieter room as my wife is calling it) then making sounds.
But I think it is the best way to know the working of every part of this system.

That's a solution. But the correct way would be to adjust the A-155 so that
it outputs 1.0V in 1V mode. For this a trimming potentiometer (P9') is
available on the upper A-155 potentiometer board.
