Hi Rich,

Right, some Band-in-a-Box styles use RealTracks, which are audio, and some styles are MIDI-based, so all the tracks will be MIDI, but this doesn't mean that the songs are MIDI files. They just use MIDI styles.

What color are the track names at the top of the screen (Bass, Piano, Drums, etc)? Green means RealTracks, yellow indicates MIDI.

What exactly do you have selected for all the tracks in that "Select Ports/Instruments" window now?

Thanks
