CAN I MODULATE THE PITCH AND FILTER CUTOFF WITH AN EXTERNAL AUDIO SIGNAL?
Yes. To modulate the pitch, you must plug your audio signal into the VCO FM IN. To modulate the filter cutoff, you must plug into the VCO fcM IN. Results will depend on the input material. Go easy on the level until the effect appears. Not necessarily musically useful, but may appeal to power electronics, weird techno and experimental enthusiasts.
