The Wah-Wah FX unit was modeled after classic wah pedals of the 1970’s. It’s a fun and versatile effect that doesn’t sound like any of the other Omnisphere Filters. This FX unit works both as a sweeping wah-wah and also as an “auto-wah” envelope filter effect by using the controls on Page 2.

Unsynced: 0 to 8.8Hz
[SWEEP LFO] DEPTH
Controls the sweep range of the LFO sweep. Range: Off to 100%
[SWEEP LFO] SYNC
Engages and Disengages synchronization of the LFO rate with the host’s tempo.
Controls the Center Frequency range of the filter wah. Range: -10 to +10%
Controls the Resonance or emphasis of the wah frequency. Range: -10 to +10%
A phase reversal that inverts the left and right modulation for a stereo wah effect.
PAGE TWO CONTROLS
[AUTO ENV] THRESHOLD
The audio level at which the Envelope Follower modulation begins. Range 0 to -90dB
[AUTO ENV] ATTACK
The time of the Envelope Follower modulation beginning slope. Range 200 to 8000 ms
[AUTO ENV] RELEASE
The time of the Envelope Follower modulation ending slope. Range 25 to 1500 ms
[AUTO ENV] POLARITY
The polarity of the Envelope Follower modulation. Choices: HIGH/LOW, LOW/HIGH
Drop-down menu that allows a choice between LFO and AUTO-ENV as source of Wah-wah modulation.
Adjusts the overall output volume. Range: 0 to 13 dB.
