Hi,
Just wanted to chime in to say that I’ve encountered the same Program Change issue with UWP and reverting to MME solved it.
Unfortunately, I also use a Bluetooth MIDI interface which is only supported with UWP. Not an ideal situation…
@msmcleod If this is a Microsoft bug, hope you can report it upstream.
I’m running BandLab Cakewalk 2021.11 (Build 018, 64 bit) under Microsoft Windows 10 21H1 (19043.1387).
