[chuck-users] Chuck and Control Voltage ( CV )

[Stefan Blixt]

My experience was that the soundcard maxed out at +-4V. That was enough for
me; at 1 V/octave that means 8 octaves for notes and enough amplitude to
give the VCF a thorough sweep. It simple in ChucK too: the difference
between 0.0 and 0.25 is 1 octave, between 0.25 and 0.5 is 1 octave and so
on.

I don't know how to test the voltages without a scope or a meter - nice
gear to have around when working with CV anyhow. Maybe you could feed the
voltage back into an input and have silent way calibrate it for you (if it
can do that), though I've found the inputs on the MOTU to be less reliable
than the outputs.
