Well of course, but that's true of any voltage. The point is that the level input has no way of interpreting a 1v/oct protocol in the way that an exponential pitch input does.

That makes sense in exponentia= l inputs of VCOs and VCFs, everything else is simply measured in voltages, = and sometimes the response curve, like log, lin or expo. In my experience m= ost cv outputs in eurorack 10vpp, being 0 to 10v if positiv only, and -5 to= +5 if bipolar, though there are plenty that output double that (-10 to 10)= . Inputs often can be set to respond linearly or log/expo and often go thro= ugh attenuverters. And a system is never complete without utilities for con= ditioning voltages to what you need. I have quite a few voltage processors = myself which I use for attenuation, inversion, offset, amplification, mixin= g etc... > > > > Sent from my iPad > > > > On Sep 29, 2019, at 12:09 AM, DJ Maytag <xxxxxxxx@xxxxxxxx.xxx> wrote: > > > > The only use I could see for a 1V/oct input on a VCA is if you want som= e intentional bleed/droning as you play higher up on the keyboard. > > > > The second use wouldn=E2=80=99t be on the VCA itself, but on an envelop= e/ADSR controlling a VCA.
