Hi Peter, I think I may have stumbled across a bug this evening. I was hosting a session and the other guitarist has his own lyrics and midi changes at the start of each song. All works fine as it should unless I am using a backing track file and in which case his local lyrics file does not seem to send his midi change and change the preset on his floor modeller. There’s no issues with the midi syntax. It just happens when I am using backing track for some reason and works fine on all the other songs.
