AW: [Re: thermal tips re expo converters:]

One good feature of a V/Hz system is that linear through-zero VCO's
could nicely be used to do dynamic depth FM with very high modulation
indices ( unlike expo-VCO's which have linear FM inputs added afterwards
). Maybe reset the 2 "operator " VCO's at the start of each note to
start out with the same initial waveform phases. A board containing 2
through-zero VCO's, 2 VCA's and 2 env generators would be a neat module.
