All has been going well with my setup for months but now I’m getting occasional problems with a stuck midi note. It’s happened once at each of the past two band practices. In the heat of the moment, I have not gathered much information. I do know that it’s happened on the same keyboard, but with different plugins. I don’t think it was the same keyboard key but I can’t say for sure. I unplugged the USB cable but the note continued. I switched states in the song- still stuck. Then I switched songs and it stopped.
What steps do I need to go through to trouble-shoot this?
