BUT my BIAB 2024, doesn't work this way :
- I can open a MIDI file, but not with F7,
F7 has been repurposed, the FAQ is out of date.
Also, opening a MIDI file is now done via File->Open Special->Open MIDI File.
The FAQ is also out of date on that; A quick check opening a MIDI file by that method also doesn't seem to behave as the FAQ suggests! (Sheesh!).
Charlie's method works quite well, either from File->Import->Import Melody from MIDI File
or Melody->Edit Melody Track->Import Melody from MIDI File
Using Charlie's method you can set the BIAB destination tracks for the various MIDI source tracks.
