Hello there
I recently got a DDrum AT Module from 1993. Everything is working great except the main potentiometer. I tried to open the module and check for anything strange, but I encountered a problem : The potentiometer is not dead, resistance values changes everytime I turn it. So I tried to follow the 3 traces coming out of it, and I saw no corrosion on the board.
This is where I'm into a deadend. I can't see where the pot's traces are ending, and if the potentiometer is working, what could be the faulty component ? Also I'm unable to pilot this thing via MIDI, since the prog change setting is set on off, and thus the module won't recieve anything except note on/off.
Thanks in advance !

Hi
I'm not familiar with the AT, so the only advice I can give, is to download the manual (links in the manual section of the forum).

What one is the main potentiometer? The big one in the middle should be an encoder.

your issue is you cannot set prog change to enabled because the main "potmeter" does not let you select it?

Prog change is only to control other gear with your ddrum not for incoming midi. You want to trigger a ddrum with audio and not with midi - otherwise you dont get to access the lower dynamic registers and the link modes are not as advanced. Try running another drummachine with many outputs as a master without midi. If you use midi - check what channel it receives its midi. Never had issues there.
