Hey Limor & The Gang, any way of adding PWM? I'm guessing that a resistor somewhere changed for a pot would allow variation of the Pulsewidth?
That'd be mucho funkio! So whuch resistor controls the pulsewidth????
PWM

Check this out.

Assuming you set the waveform to saw, and interposed this circuit between the filter, it might work with some modifications.
You're probably going to have to muck about with the resistor values because they're using a 15 volt supply, while the x0x has a 12 volt. Also, the output voltage on the PWM unit is +5V to -5V, while the x0x is expecting a range between +5 to +9 or +6 to +11 depending on the waveform you selected.
