Help! I've still got one problem. When I imported the MIDI file (which sounded exactly like an upright bass in Windows Media Player or other programs, which is what I wanted), it came in as "instrument 27 Jazz Electric Guitar". I can't figure out how to change this back to an acoustic bass. If I try to "select Real Tracks", the bass track that I select plays its own melody, rather than the notes that are in the MIDI file. How do I fix this?

Thanks again!
