[sdiy] VCO Linear Voltage

[Jerry Gray-Eskue]

Thanks for all the response to this question.
I now have a lot more respect for VCO Linear inputs.

Question:

How is the linear voltage control of frequency useful on a 1 volt per octave
VCO?

Thinking about it, this control input is not making musical sense as it
varies the output frequency at a direct relation to the voltage in. In other
words at low frequencies the variation in Cents will be much greater than
the variation at higher frequencies. The rapid fall off of relative
variation would seem to make it an undesirable type of control.

What am I missing here? Is this useful for modeling the timber of some
certain instruments or perhaps other acoustical artifact?
