Yeah right...upside down as usual (-;
I was trying to say that if you put in 1 Volt you could get (depending
on your initial offset) 440Hz and then at 2 volts you get either 880Hz
(an octave) on one type of analog synth or 540 Hz (440 + 100 at
100Hz/Volt) on another.
That is to say, frequency in an analog synth is determined by
offset+(Octave/Volt) or offset + konstant*(Hertz/Volt).
Anyway, there is no absolute frequency in an analog synth the way there
is in a digital one, and the ratio is usually adjustable too so
alternate tunings are much easier to implement.
