I've been going back and forth with Tech Support. BIAB (and other GM players, including MS Media Player and VanBasco's MIDI Player) play back the files perfectly but PTPA12 drops drum beats, even though you can see the beats being executed in the Drum Kit window.

This is really screwing me because now I can't use PT live. I need the multiport capability to send out MIDI messages to a chain of devices. PT has the multiport capability, BIAB does not.
