Apple has updated MainStage to v3.2.2.

Changes:

• Includes several fixes to enhance stability and reliability.
• Fixes an issue introduced in MainStage 3.2.1 that could stop some Concerts from opening.
• MainStage no longer quits unexpectedly when changing from one preset to another when using the Vintage B3 Organ plug-in.
• A stereo instrument that's panned to the right now sends the correct signal to the left mono output.
• The Progress Indicator screen object again works as expected.
• Mappings to aliases are now saved properly in patches that contain multiple aliased channels.
• Pasting an external channel strip as an alias no longer causes unexpected duplicates of channel strips.
