I'm using Logic to playback audio tracks in live performance. No MIDI tracks. No Softsynths. Nothing but about 3-4 audio tracks. I call up the song files using Onstage. The floor controller used is the pedal board from my guitar rig. An Axess FX1. Everything works fine with one exception. Somehow in some instances a fader will respond to the volume pedal in my guitar rig. (CC#7 on channel 3 that I've seen so far.) This causes volume on the track to drop to zero in some cases as I call up guitar patches that might use that CC#. All of my track playback commands (CCs and PCs) are sent on channel 15. The guitar rack uses other MIDI channels. I'd like Logic to ignore all MIDI channels EXCEPT channel 15. That would solve it. But I can't find where to assign or unassign MIDI channels in Logic. How do I get Logic to ignore all channels except channel 15?
