Sustain Pedal causing CPU Overload for Audio Units (AU) only
Mainstage 2.2.2 has a CPU overload with any AU instruments I am running. All are legit for example Modartt's PianoTeq. It is actually manageable at about 60%. However, the moment I use the sustain pedal for about a bar of music, it spikes and then has audio dropout making it impossible to play.
I have made the settings to allow 256 samples as buffer size. Even after going to 512 samples, the CPU spikes are prominent.
I tested out the default keyboard concert with tons of patches loaded with the preset sounds. The pedal works fine and CPU usage doesn't cross 15%!!
I'm pretty surprised since the upgrade has cause this problem. All earlier versions of Mainstage ran fine.
Is there:
Any solution to this weird problem?
Any way to revert back to an older version which works fine on 10.7.4?
