MainStage audio cuts out completely
Periodically, MainStage runs great then after sitting untouched for a while (+/-60min) MainStage no longer outputs audio to any source. MainStage still reads midi, computer still plays audio perfectly from other applications; sleep is turned off so during periods of unuse MainStage remains open and in exact same state as when used. Panic button does nothing, restarting application gets sound working again. I'm using MainStage 3.6.1 on MBP (OSX 12.0.1)--any ideas what causes this issue?
