On an M2 MacBook Pro, running Sequoia 15.3.1, MainStage 3.7, MIDI Guitar 3.0.61, if I have a patch with a software instrument that is getting input from MIDI GUITAR OUT (1-16), the instrument works, but the MainStage UI becomes very unresponsive and there are lots of spinning beach balls. If I turn off the MIDI Guitar 3 plugin, the MainStage UI becomes responsive agin.
UI response is better, but still sluggish, if MIDI Guitar 3 is on, but no patch that uses it is selected. As soon as you select a patch that uses the MIDI GUITAR OUT, UI performance degrades badly.
MIDI Guitar 3.0.62, and possibly MainStage 3.7.1 seems to have addressed the UI response issues. However, now MIDI Guitar 3 seems to be causing some MIDI feedback loops. But that seems to have stopped to. Working great right now. I did change it to channel 2 so it wasn’t in the same channel as my MC8 which is controlling Helix Native.
