The other cc numbers are ignored, but it would be easy to link them to the other 3 sensors. And in Clouds engine they could directly control the 8 most useful out of the 10 parameters available.
That would be so awesome to have!
Even though most controllers only have 8 faders or knobs, you could enable CC for all 10, then users can just assign the CC's they want on their controller. (I also suspect that some folks would like to be able to control everything in their DAW through MIDI)
I recently decided to learn piano/synth improvisation, so I bought the Arturia Keylab MkII keyboard. It has 61 keys, pitch wheel, mod wheel, aftertouch (although I don't use it because I feel it lacks fine grained expressivity), sustain pedal input, expression pedal input, 9 knobs and 9 faders.
It is super easy to configure the knobs, mod wheel, expression pedal and faders to specific CC's.
If you are going to work with the MIDI implementation later, then I would also like to add 'sustain' to the wish list

...
For example if you make a chord, then you could just tap the sustain pedal and then both of your hands would be free to use the sensors.
