Stop MainStage changing audio drivers
I have an issue with MainStage changing audio drivers in the middle of a performance, hence stopping sound. I have a YAMAHA YC73 keyboard, which came with audio drivers (YC Audio) allowing Logic Pro to record audio via USB. My live config is based on MainStage, with audio output to a Presonus mixer. However MainStage often decides to change the IN/OUT drivers to "YC Audio", which results in no audio output for the whole setup. Pretty annoying on a live performance!
Is there a way to force MainStage to use ONLY the Audio iN/OUT device that I enter in Settings and stop switching to others as he pleases?
