Yes, The package you bought looks to be the midi-only version. BIAB has versions now that have "real tracks" in them that sound great -- but they cost a lot more.

Now the midi stuff will sound pretty good, too -- if you have sound modules that "interpret" the midi directions into good sounding audio. Just remember that midi is just 1's and 0's -- no sound at all. Your default PC soundcard has the standard general midi mapping that, well, sounds cheesy.

Don't despair -- I think you can make drums, bass, piano backing tracks that can sound pretty good with just about any flavor of sound card. I'll be out of town for a few days, but the folks around here are friendly and will help you out.

P.S. Here's a few "bluegrassy" type tunes I did with BIAB real tracks as the backing band:
