Auto-wah

Plugin screenshot

Fomp is an LV2 port of the MCP, VCO, FIL, and WAH plugins by Fons Adriaensen. The auto-wah, is basically a combination of an envelope follower and a resonant lowpass filter. For increasing level both the frequency and the bandwidth of the filter will increase. How much is controlled by 'Drive'. For a normal wah, use a pedal to control 'Frequency' and set 'Drive' to zero.

Control Default Min Max
Drive 0.00 -20.00 20.00
Decay 0.00 0.00 1.00
Range 0.50 0.00 1.00
Freq 0.25 0.00 1.00
Mix 0.75 0.00 1.00
