A seemingly simple question, with a seemingly simple answer too. Certainly,
the FM inputs on the VCO are perfectly suited for such an application. Any
CV source into these inputs will "bend" the pitch of the oscillator. While
many pedals may not go back exactly to zero, you would want to tune the
oscillator with the pedal plugged in the full back position and then use the
FM knob to set the upper end of the bend range with the pedal pushed all the
way forward.
Of course, you need a CV pedal (simple). You could buy a CV pedal, or hack 4
"AA" batteries into a guitar pedal. Or use a pedal interface module
(snicker). Paul has promised us one. To possibly speed the process, I am
sending along a prototype of my pedal interface module for consideration.
Or, if you just have a regular guitar volume pedal, use something like the
MOTM-800 output for your 5 volt source and plug that into your guitar pedal
input. Take the guitar pedal output and run it to the VCO FM input. Not
perfect, but it will work.

If this would work is there a way to "tune" it so that
when the pedal is all the way back there is now effect
on the VCO, and when the pedal is pushed all the way
forward it increases the pitch a full octave? This way
you could be playing along and just stomp on the
pedal and get some neat "wammy bar" effects.
