Connect an expression pedal to the Pro 3 and route it to a parameter such as filter
cutoff in the mod matrix for more real-time processing control over the audio input.
Filtering External Audio Using the Envelope Follower
The Pro 3’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
ext in env
tab. Display these parameters by turning the
ext audio
knob in the Mixer.
