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

Sub octave
knob on the
front panel.
