Just got an MC6 and have been programming it like crazy. I have two expression pedals connected, and they work great individually, but if I move them both at the same time, one is always blocked/frozen until the other one stops moving. Is this by design or a perhaps a hardware limitation? I've tried assigning the pedals to separate MIDI channels but it didn't help. I thought maybe it was a limitation of MainStage, but I tested the same scenario with an FCB1010 and the expression pedals work simultaneously as expected.
