It does indeed!
I think the best way to achieve this kind of control is to have a
continuous optic distance sensor. This can give you acceleration
output and position output.
Imagine having a synth style keyboard with the position going to the
volume of the voice, and the speed going (through a non-symmetric LPF
with a long release) to the volume of the suboctave. This would be a
great lead/pad patch.
