After 3.2 update inputs from external instruments is not saved.
I have some concerts which use both software and external instruments. The external instruments are a Yamaha MOTIF XS Rack and the Akai EWI 4000s. If I open my concerts (saved in the previous version of MainStage) everything works as before. But if I make any changes and save all my patches which use external instruments all the inputs are missing. If I manually select the input I can hear the instrument, but it will never save that setting even if I create a new concert and select an external instrument for a patch. This is a major problem as I have dozens and dozens of patches. This is ridiculous.
