Connect the MOXF to your computer via USB.
You’ll need the Yamaha Steinberg USB Driver for Mac.
You’ll need to address the external synths through your setup in Logic.
Create a MIDI Track for each device you want trigger from the MOXF... Assign each so it is receiving MIDI IN from the MOXF-1 (Port1).
Assign the MIDI OUT to the device you want to trigger... one per Track.
You’ll need to *select* all of the Tracks to transmit to them simultaneously.
