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.
