Running 2 Midi Keyboards Into Mainstage - Midi Signals Get Mixed Up
I'm running two midi keyboards into Mainstage 2 on a Macbook Pro. My midi interface is the Midisport 4x4 Anniversary Edition, and my audio interface is the Metric Halo ULN-2.
I want to run my setup as if each keyboard was a different sampler, so I've set up each keyboard in Mainstage's layout. Each physical keyboard runs into a different channel on the midisport, and in mainstage, each keyboard has its own sustain pedal, a control pedal, a pitch bend wheel, and a modulation wheel. I linked each physical controller to it's software equivalent by the Learn feature.
I set up 2 different software instruments in Mainstage– one controlled by the first keyboard and the 2nd controlled by the 2nd keyboard.
The issue is that the sustain pedal, the control pedal, the pitch bend, and the mod wheel of one keyboard affects the sound of the other keyboard's sampler, and vice versa. Do you have any idea why this is, and how to prevent it?
