I am a new user. The program mostly works fine. The sound is MOTU ASIO. Once a file "goes bad," it always bombs when I try to generate & play. However, when I delete a few chords, it seems to work. Lots of jazz extensions, maybe they are "killer chords." (Maybe it doesn't like the b13?).
Seriously, it is odd behavior. I will try to return to factory settings, as suggested.
