Motion Filter

[Elias Holman]

A very simple implementation of a motion filter is a envelope follower,
essentially, a diode, a resistor and a capacitor, which controls the
cutoff fq of a VCF.  Essentially, the current amplitude of your sound
changes the current timbre, giving your sound a "timbre envelope", it's
a pretty neat effect.  If you want to hear an example of one, check
out "Make My Funk(the P. Funk)" by Parliament on the Mothership Connection
album, or basically get a Bootsy Collins album, at least one of the songs
will make use of the Motion Filter.  It's pretty funky.
