"Additive" midi messages

[Bigbee]

I'm making an insect instrument. I want to replicate the process of an insect rubbing its legs together (or rubbing its head on its abdomen or rubbing one leg against another). Ideally, I'd like to use a slider or potentiometer to do this.

The instrument would behave like this: move the slider up and down slowly and a sound begins to resonate, move it faster and it resonates louder or the sound changes depending upon how fast the slider is moved up and down. Any ideas?

The wall I'm running into on my first attempts concern the linear scaling of a slider/knob. Is there were a way for a controller to tell Ableton: Faster = Louder?

Thanks!

That's a tough one, but probably a job for Max for Live...maybe want to ask in that forum if anyone can help.
