Maybe one of you digital audio whizes can help out an old audio guy with a technical glitch who's trying to get back into recording and composing after a 20 year hiatus.

I've just begun to use Logic Platinum on my G4 Quicksilver w/dual processors. After laying down a couple of orchestra parts, the whole audio starts to distort, then cuts out completely.

A Logic error message then pops up, saying: "Error while trying to synchronize Audio and Midi." Then it shows some sampling rate number, after which it says, "Check conflict between Logic Platinum and device."

What device? Is there a conflict with my audio/midi interface? Or is it my keyboard/controller that's the culprit? Could it be my Kontac sample player? Where do I go in my computer files to correct this? I can't seem to record more than a few trax before it locks up and shows another error message.

Any suggestions? I'm new to the whole digital audio thing because when I left the biz it was all still analog, so be clear and specific with your directions.
