Hmm, I'm finding now that if I create a new song then CoyoteWT kind of works, but it won't let me change the patch once it's loaded, and it doesn't work at all if I try and use it on a song I made before the 2021 upgrade. I've tried a factory reset but that didn't have any effect.

In general, I've struggling big time with MIDI in BiaB since the 2021 upgrade, in all sorts of ways. Many things that used to work fine no longer work. I don't know if it's something peculiar to my set-up, but presumably so since most other people don't seem to be having these issues. Is there any kind of tech support webchat available?
