Re:MIDI Drum files have weird timing issues in X1
I solved the problem, in case you ever read this. The problem was with the Soundblaster Audigy Platinum card I have installed and was using on this particular computer. I installed my old Roland UA-100 and use it in ASIO mode and the midi all plays perfectly now. All of it, including the Prosonic drum patterns. So once again Soundblaster, a non professional audio card, is the culprit. Hope your situation got resolved.
