If you've got a basic sawtooth wave, you can add a sub-octave 
squarewave to it to generate a sub-octave sawtooth wave. The sawtooth 
"fills in" the missing harmonics of the square wave and makes it a saw. 
I've also tried starting with low frequency triangle waves and using 
precision rectifier circuits to generate triangle waves an octave 
higher.
