Short answer: Yes, BIAB will do what you want (and, of course, much more). You can loop tracks and play as long as you want. You might want to investigate the Conductor function for more control of real-time playback.

Real Tracks will sound from slightly to dramatically better than MIDI tracks, depending on the quality of the GM wavetable in your sound card.

I hope you make the choice to come aboard. It's a great product and a great community.
