T.WAH (Touch Wah)

You can produce a wah effect with the filter changing in response to
the guitar level.
Parameter/
Explanation
Range
MODE
Selects the wah mode.
LPF This creates a wah effect over a wide fre-
(Low Pass Filter) quency range.
BPF This creates a wah effect in a narrow fre-
(Band Pass Filter) quency range.
POLARITY
Selects the direction in which the filter will change in response to the
input.
UP The frequency of the filter will rise.
DOWN The frequency of the filter will fall.
SENS (Sensitivity)
0–100 Adjusts the sensitivity at which the filter
will change in the direction determined by
the polarity setting.
Higher values will result in a stronger re-
sponse. With a setting of 0, the strength of
picking will have no effect.
FREQ (Frequency)
0–100 Adjusts the center frequency of the Wah ef-
fect.
PEAK
Higher values will produce a stronger tone which emphasizes the
wah effect more.
0–100 Adjusts the way in which the wah effect ap-
plies to the area around the center frequen-
cy. With a value of 50 a standard wah sound
will be produced.
LEVEL
0–100 Adjusts the volume of the effect sound.
DIRECT LEVEL
0–100 Adjusts the volume of the direct sound.

AUTO WAH

This changes the filtering over a periodic cycle, providing an
automatic wah effect.

fect.
PEAK
Chapter 9 Parameters Guide
Parameter/
Explanation
Range
0–100 Adjusts the amount of wah effect applied in
the range near the reference frequency.
Higher values will produce a stronger tone
which emphasizes the wah effect more.
With a value of 50 a standard wah sound
will be produced.
RATE
0–100, Adjusts the frequency (speed) of the change.
BPM –BPM
When set to BPM, the value of each parameter will be set according
to the value of the BPM (p. 163) specified for each patch. This makes
it easier to achieve effect sound settings that match the tempo of the
song.
* If, due to the tempo, the time is longer than the range of allowable
settings, it is then synchronized to a period either 1/2 or 1/4 of that
time.
DEPTH
0–100 Adjusts the depth of the effect.
LEVEL
0–100 Adjusts the volume of the effect sound.
DIRECT LEVEL
0–100 Adjusts the volume of the direct sound.

OCTAVE

This adds a note one octave lower, creating a richer sound.
* Because of the need to analyze the pitch, chords (two or more sounds
played simultaneously) cannot be played.

string) to E4 (corresponds to the sound of an
open 1st string)
RANGE4 B1 (corresponds to the sound of an open 7th
string) to E3 (corresponds to the 4th string
played at the 2nd fret)

below.
DIRECT LEVEL
