Thanks for the reply Ian.

I can swap out the drums for different styles, both RealDrums and MIDI, and I hear both.

Regarding an all midi style - I'm not sure how to select this: I go to the Song Selection window, and the categories I have include Name, File Name, Melody and Style. I can't select MIDI/Real from here.

However, if I select any song and load it, I hear only drums. If I then change the style, and choose only MIDI styles, still I hear only drums. However, if I then change to a RealTracks style, now I hear all instruments, and all instruments are green.

Hmm... ok, something to do with the MIDI settings. I think this is related to CoreMIDI setup, because if I instead select Apple DLS, then it works (but sounds very basic). I use MIDI a lot in Logic Pro, and have a large number of sample libraries that I use there, so MIDI seems to be working fine, but clearly something wrong with my MIDI settings in BIAB. I've tried different ports, but nothing works when I have CoreMIDI selected.

Thanks again,
Garry
