novice and the oscillator

[Tom Priore]

Thanks for the info. I'm pretty familiar with how to build everything you
described but the oscillator itself. how do I go about making the
oscillator?
And a question about the CV, If 1 volt is an octave of pitch, then obviously
for every one volt increase of the cv, the frequency of the oscillator is
doubled. This sounds pretty tricky.

The basic concept of most VCOs is based on a simple saw tooth oscillator
controlled by an input signal called a CV (Control Voltage). A standard CV
usually represents 1Volt per octave of pitch. The saw tooth oscillator will
sweep linearly upwards from something like 0V to 5V. When it reaches 5V, it
snaps back to 0V and continues. The input CV determines the rate at which
the VCO saws upward and thus the frequency of the VCO.
