Title: PMI DMX88 Mux Post by: obsoletemachines on April 12, 2015, 09:08:46 AM hi, has anyone got a source for this chip?
I have a drumulator which has its fair share of problems. Reset was out on CPU so i replaced CA3086. Then the Rom was scrambled so i obtained a fresh Rom. Then the sounds were distorted so i attended to the TL084 buffer op amps. Now i get all the sounds but they are in the wrong places, eg. BD is comes out of snare. I think it has to be Demux , levels etc are fine. I'm nearly home and just wish to bring this over the finishing line. So, if anyone can help on this chip i would be grateful, eternally.
