Hi,
Thought I would update this thread and see if anyone has any further thoughts. Spoken to apple support and supposedly MS does respond to bank change messages. I'm not sure what the exact parameters should be though. If anyone has any interest in exploring this problem further, I attached a screenshot to show my process. If its helpful I can post screenshots showing the midipipe process or set up a link to it. am following up with apple support and will post any updated info as I learn it.
I've seen a lot of posts online regarding this issue with people trying to resolve it but have yet to confirm that anyone did or that bank change actually works so it could be this is a bug within MS. I'm a little surprised there isn't a midi implementation chart for MS of some kind.
**one note is that the program change message by itself does navigate to the correct patch, but after sending the bank message it does not, suggesting that MS is receiving the bank message but it does not have the correct parameters. Any info or thoughts on what those might be or if there might be bug in MS would be extremely welcome!
Thanks,
Ben
