As you would need a gate output to enjoy the midi fully, i would see things like this
Minimal expension module ( 2hp )
- Midi Trs in
- Midi gate out ( to trigger enveloppes )
- ... any suggestion ?
Maximal expension module > 2hp
- Midi Trs In ( Thru ? )
- Gates... 1, 2 ,3 4
- Separated voices outputs ( i mean 4 not 24. so you would get max 6 unisons voice per output )
I could definitevely add a port at back of the module to make this append next.
But adding midi as the module is ( 10Hp ). I dont see usecase it would be nice except making it a synth voice, and it is not the goal. Tell me if you do not agreee
