the description in the Serge catalog has influenced me to include
a compressor in my own FS, so I'll jump in here. Even the best
FS produces some bleedthru, i.e. the VCO frequency is not
completely cancelled (as it should according to the formula that
was recently posted). Bode (the classic one) used a "Squelch"
function (sort of noise gate) to get rid of tht annoying noise in
silent parts of the input signal. The Electronotes FS did a similar
thing. The Serge approach is much better: like a Dolby or DBX
noise reduction, the input signal is first compressed, then
processed in the FS, and then expanded. So the noise is reduced
in silent parts, but you don't have a hard gating.
I never heard a Serge FS - I just took the idea from the verbal
description - but in practice that derived version works fine.
BTW, Serge once wrote in EN that he also used companders in
his Ring Modulator and Phaser. Anybody has seen schematics
for this ?
