OK, the Display glitches seem to be normal - fine.
Weird things happen in regard to the Potis:
I recognized, the value jumps and occasional "double Assignments" seem only to occur, when th Pro2 is sequenced by Live9 via the USB Midi. When those errors happen, and i stop the Playback in Live, immediately the Pots are working normal.
I will do some testings tonight: changing USB Port on the PC, using only direct Midi from the PC/no USB at all.
Another Question:
is it normal, that Parameter automation in the Daw controls only the last selected Pot/Parameter? E.g. i tweak the cutoff and record the automation in Live. As soon i touch another Pot (eg. Amp Attack) the previous Cutoff automation controls the Attack. This is weird and wrong. Are those Glitches according to each other?
thx for your answers!
