Quick follow up - I had to do a RTFS to test out the audio recording feature, so I thought i might re-test the previous issue with clean factory settings:

This is what I did:
- created a track in Cmaj, 4 bars, C only, 3 choruses
- selected a style with 5 instruments _BIGTIME
- generated, played - all ok
- selected saxophone track, changed RT to Best Sub (3448 Flugelhorn, very nice) - regenerated and played ok
- for the newly updated track, changed AutoFix Sour Notes to 'Song Chords' - BIAB crashed (not responding)

That's all from me for this topic :-)
