I'm interested in what the range of the modulation-amount knob and
associated CV ought to be. The core sees one linear control current,
which comes from an exponential function of V/oct CV multiplied by a
linear function of modulation CV. I'm interested in knowing what values
of the modulation-CV coefficient are useful. How much deviation, compared
to the carrier, do people want to use in practice? At maximum deviation,
how much does a volt of modulation CV change the frequency?
It should go without saying that I mean when the carrier frequency
is nonzero.
