Filtering External Audio Using the Envelope Follower
The Pro 2’s envelope follower makes it easy to process external audio
with an “auto-wah” type effect. Add a little distortion and delay and this
is a very expressive effect.
The Envelope Follower has controls for
attack and releaSe in the Sub oSc
tab. Access these parameters by turning the oSc 1 Sub octave knob on the
front panel.

To avoid continuous oscillator drone, set the output level of all Pro 2 oscillators
to zero. Alternatively, set the waveshapes of each oscillator to osc oFF.

5. With soft knob 2 (Source) choose envelope follower as the source.
6. With soft knob 4 (deStination) choose f1 cutoff (or f2 cutoff if
you’re using Filter 2) as the destination.
