Hi All
I think I have it sorted.
If I put the chords into BIAB myself I can assign real styles to it then it plays the real instruments.
Yes, you will hear RealTracks playing on your chords.
What I should do is load my midi file and choose real styles then will it play the real musicians.
No, it won't use RealTracks to play your MIDI file. If you want to hear your MIDI file, put it on BIAB's Melody and/or Soloist tracks, and assign a MIDI sound source (a hardware or software synth). You can do the same thing in your DAW by assigning a MIDI track and selecting a MIDI synth.
I know I can't get audio tracks to act like midi.
Correct, not in BIAB. However, there are a few other programs such as Melodyne that can do some functions.
