Re: [AH] Why isnt everything 1 v/o ?

I presume by 1 v/o you mean 1 volt per octave. While this makes sense for oscillator or filter cutoff 
frequency it does not necessarily make sense for a VCA or other module without a common unit of 
calibration. A VCA could have a logarithmic, linear or other non-linear control law for the gain. To calibrate 
a logarithmic control to 1V/6dB gives a gain range of 60dB over the typical 0-10V control source range 
which is not adequate to fully cut off the sound. To allow for this a VCA will often have a voltage mixer for 
the input control voltages to allow them to be scaled to the desired control depth.
