009: Wah/AutoWah
This stereo wah effect allows you to create sounds from vintage
wah pedal simulation to auto-wah simulation, and much
broader range settings.
a: Frequency Bottom, a: Frequency Top
The sweep width and direction of the wah filter are determined
by the “Frequency Top” and “Frequency Bottom” settings.
b: Sweep Mode
This parameter changes the wah control mode. Setting “Sweep
Mode” to
Auto will select an auto-wah that sweeps according to
envelope changes in the input signal level. Auto-wah is fre-
quently used for funk guitar parts and clav sounds.
When “Sweep Mode” is set to
D-mod , you can control the filter
directly via the modulation source in the same way as a wah
pedal.
When “Sweep Mode” is set to
LFO , the effect uses LFO to sweep
in cycle.
c: Envelope Sens (Envelope Sensitivity)
This parameter sets the sensitivity of auto-wah. Increase the value
if the input signal is too low to sweep. Reduce the value if the
input signal is so high that the filter is stopped temporarily.
c: Envelope Shape
This parameter determines the sweep curve for auto-wah.
d: LFO Frequency [Hz], e: BPM/MIDI Sync
When “BPM/MIDI Sync”= Off , the LFO speed uses the LFO Fre-
quency parameter setting. When “BPM/MIDI Sync”= On , the LFO
speed follows the “BPM”, “Base Note”, and “Times” settings.
e: BPM, e: Base Note, e: Times
One cycle of LFO sweep is obtained by multiplying the length of a
note (
… ) (selected for “Base Note”, in relation to the tempo
specified in (“BPM”, or the MIDI Clock tempo if “BPM” is set to
MIDI ) by the number specified in the Times parameter.
