I’m not sure if this one has been floated already but having “macro” sliders that can control multiple sliders within OSC/Pilot would be very cool and possibly solve a few requests.
Ableton’s “map” function which also gives varying min/max to each target is really cool.
controlling multiple synth parameters(with varying amounts)with one slider
controlling multiple RGBAW values of a led
sending multiple OSC/midi values from a single source
