But 1 V/octave - that's outside your synth, right? It enters through a
resistor and becomes a current, and it's up to you to do something useful
with it.

*Generating* CVs is another story though. Hard to do without enough supply
voltage. :-)

Why not 0.198679797 V/octave, like the 2164 VCA has at room temperature?
Sounds like a good internal standard. (-:
