-In Logic create a multi-timbral software instrument with 6 parts (Tracks 1-4, FX, CV)
-Load Overbridge into the track as a multi-output instrument.
-In the mixer view press the + icon of the track 4 times (or 5 if you want to use the external-in track).
-Now you have individual tracks.
-To record them send them to individual buses and make audio tracks with those buses as inputs.
-Remember to stop the voices from going to the main out so that you can have a stereo fx track with none of the dry signals.
I can only get 1 machine working at a time and the sync makes it unusable in combination with other sound sources
