Originally I was thinking about a
control to set the base frequency, but it sounds like you are
thinking about adding a Hz frequency CV port. This is a better idea,
since you get both options, and the debate goes away entirely. The
overhead is about 2 multiplications per sample, so not really an
issue.
Careful there. You will find that to get the 1/oct modulation to work,
you'll need a calculation somewhat like this:
frequency = exp2(octave_mod_port + log2(Hz_port))
which in light of this overlong discussion, makes me laugh out
loud!
