I was running Digital Performer 3.1 on an Apple 9600 accelerated with and XLR8 processor card,
everything was fine except rather low performances. Since I replaced the XLR8 card with a Sonnet G4/450 processor card, I can't play or edit any session properly.
The midi signal disappears after a couple mesures (the sampler doesn't read any signal) and then the program becomes very instable, DP crashes and sometimes the computer crashes too.
Those problems only happen with the PCI 324 card, everything is fine with the SoundManager.
Have you ever heard that story before ?
