I'm putting my post here, because that's where it seems most appropriate:
I had a dream: I was controlling a Voltage Modular patch with a graphics tablet:
- the pitch on the X axis,
- the filter opening on the y axis
- and the depth of an LFO's effect with pressure.
I think it was the Space Controller from @ChR_is who sparked the idea, since its module is an inverted mouse!
Thanks in advance !
