Hi Sacguy71,
I am so glad for you that you managed to get your A4 working with your Doepfer system! :-)
So what was the problem? How did you solve it?
I actually do like/love Doepfer modules with the exception of the A-190-5, the MIDI module I had from Doepfer for a short while, it was the only module so far from Doepfer that I really disliked, not nice to use and partly illogically too, so I managed to swap the that Doepfer module for a Vermona qMI2 MIDI-to-CV module, so much easier and logically to use.
Good luck with the A4 & Doepfer systems and kind regards, Garfield.
