Nonlinear vs. chaotic

-speaking of which; has anyone used nonlinear transmission elements to make
the high-harmonic content of pulses or sawtooth waves more "ideal" in a
musical system? i'm doing a bunch of shockline stuff to that end at work,
but it doesn't have any immediate musical applications, so i wondered if
anyone had ever tried it.. or would cost be prohibitive?  

what i'd like to see is an audio-frequency pulse to soliton converter module..
