MTH Protosounds (AKA PS-1) is what we are talking about. Do not try to mix QSI chips (or boards) and Protosounds chips. What are the MTH product numbers that your boards came out of and I can fine tune things for you?

Did you ever consider that the Challenger chip might just be junk and the boards it came out of might be OK?

I enjoyed reading your post.
