Sens/Rate/
Wah Knob
The function and label of the first knob in the Mod Filter is determined by the
Mod Type setting (see
Figure 134 on page 407 ). When the Mod Type is an
envelope, the label changes to “Sens” and determines the gain sensitivity of
the Mod Filter. When the Mod Type is an LFO, the label changes to “Rate”
and determines the rate of the LFO. When the Mod Type is set to Wah, the
label changes to “Wah” and adjusts the wah pedal position.
Sens
When the knob is controlling Sensitivity, a higher setting will have a greater
(more sensitive) response to variations in dynamic level.
Rate
When the knob is controlling Rate, a higher setting will increase the rate of fil-
ter cutoff frequency modulation by the LFO. The range is from 0 Hz to 8 Hz.
Wah
When the knob is controlling Wah, a higher setting will have a brighter
sound, just like when a real wah pedal is pressed forward.
On a real wah pedal, the wah filter is alternately enabled and disabled by
rocking the pedal to the maximum forward position. Similarly, when the Wah
knob is moved to the maximum position the wah effect is alternately en-
abled/disabled until the knob (or an external controller mapped to the knob)
is moved to maximum again. This emulates real wah pedal behavior when an
external MIDI control pedal is used in realtime. (Hint: add a rubber stopper to
the front of your MIDI pedal to fully emulate a real wah pedal.)
Sweep Knobs The Sweep knobs determine the frequency range of the Mod Filter. The low
and high frequency values can be independently adjusted. This flexible ar-
rangement allows the Mod Filter to affect a narrow or broad frequency range,
and also enables you to tune the frequency response characteristic to match
the signal if desired.
Sweep Lo Knob
Sets the lowest frequency to be affected by the Mod Filter. The available
range is from 50 Hz to 4000 Hz.
Because the Sweep Lo frequency cannot be set higher than the Sweep Hi fre-
quency, if the Lo value is increased beyond the Hi value the Hi value will in-
crease to match the Lo value.
