Spatial Practice - Multichannel X/Y Midi Assignment




Moving back toward the goal of Multichannel audio control through the touch interface, I placed the reclaimed sub/speaker + tupperware amplifier tower behind me, with my studio monitors acting as left and right stereo as usual. 

Stereo pair:
L = Return A (Soundcard Lineout 1)
R = Return B (Soundcard Lineout 2)


Rear Channel
Return C (Soundcard Output 3/4)


I opted to run with only one extra channel for simplicity. After experimenting with a few routing options, I settled on traditional Send/Return routing for flexibility and simplicity - routing each channel independently.


Ableton Routing Setup
In this image the signal from Source channel is being sent to the
Left speaker and Rear speaker at full volume
Whilst the Right Speaker has no signal sent to it

I then moved onto assigning these sends to the surface via MIDI after altering the OSC routing setup to CC values again.





Left + Right Channel sends are both controlled by left/right gestures on the surface with the first finger.
Values are assigned so that as volume rises on one side of the front stereo pair, the other falls.

The second finger's left/right gestural movements control the volume of the Rear channel.
