Well, sure. We are throwing the word "absolute" around a lot, all I
mean is "a voltage means some frequency". The mapping is not entirely
static.

*Everything* is relative if you really get down to it :)

The ability to modulate with octaves is definitely nice. I agree with
that choice, it tends to more musical results particularly when you
start tossing audio and CV around interchangeably. It's not so nice for
setting the frequency to a particular note, though.

The oscillators actually have three CV frequency ports: frequency, lin.
FM, exp. FM. Since the FM ports provide the ability to modulate in a
moogey way, I'm thinking perhaps the ideal solution (outside AMS) is to
simply make the frequency port Hz and leave the others as-is. The
others, being FM, are purely relative.

The filters are slightly different: they also have two CV FM ports (lin
and exp), but the cutoff frequency is a control port (not CV). It might
be nice to make this CV as well, space be damned. This one port could
also be Hz, leaving the others alone.

Since these plugins have explicit FM ports, which is what makes them
nice to play with in a modular in the first place, nothing seems to be
lost by making the one absolute port in Hz and making all these
questions go away.

Sound reasonable?
