Halion Sonic Keeps Changing My Instrument

If you are still having trouble with this here’s what I did on my 10.5 pro (so I’m sorry if you don’t have the things pro has):

  1. Select the midi track where the instrument changes from the one you want to the default setting every time you hit the “Stop” button on the transport bar.
  2. Go to “Midi” (right at the top) and select “Open List Editor”
  3. Delete all the Programme Change and Controllers at the top and
  4. That’s it. Your selected Halion Sonic sound should remain in place now.

I hope this helps!
