The ASM-1, however, does (or can if you wire it that way). I have, in
fact, hardwired the output of VCO 1 (the sawtooth out!) to the PWM input
pot of VCO 2 on one of my ASM-1s on account of I love this sound and use
it all the time. note also crazy feedback loops with this kind of thing
can lead to even more partials and pseudo-random, pseudo pitch dependant
behavior. I'm taking about stuff like using the VCO#1 -> PWM VCO#2, then
taking VCO#2 output and routing it back to the FM input of VCO#1, and
into the filter input. Then taking the filter output and routing it back
to the sync input of VCO#2! - Have fun.
