FX (Effects) Chapter 8 Parameters Guide
Chapter 8
AUTO WAH
This filters the sound over a periodic cycle, providing an automatic
wah effect.
M-TRON III
This models a Musitronics Mu-Tron III. Filter movement
corresponds to the intensity of the input, producing a touch-wah
sound suited to funk
.
The original used monaural input and output, but on the VB-99 this
is enhanced to stereo input and output.
Parameter/
Range Explanation
MODE
Selects the wah mode.
LPF (Low Pass Filter) This passes only the low band.
BPF (Band Pass Filter) This passes only a specific band.
FREQ (Frequency)
0–100 Adjusts the center frequency of the Wah ef-
fect.
PEAK
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,
BPM –BPM
Adjusts the frequency (speed) of the change.
When set to BPM, the value of each parameter will be set according
to the value of the BPM (p. 142) 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.
Parameter/
Range Explanation
MODE
This chooses the type of filter.
LPF (Low Pass Filter) This passes only the low band.
BPF (Band Pass Filter) This passes only a specific band.
HPF (High Pass Filter) This passes only the high band.
DRIVE
This chooses the direction of filter movement during the attack.
DOWN Moves in the low-band direction.
UP Moves in the high-band direction.
PEAK
0–100 Adjusts the intensity of the filter's idiosyn-
crasies.
DEPTH
0–100 Adjusts the range of variability for the filter
according to the input level.
The DEPTH parameter is sensitive to
input. Adjust it as appropriate to
match the intensity of touch and the
style of play.
RANGE
0–100 Adjusts the range of filter movement.
LOW on the original corresponds to around
25, and HIGH to around 75.
EFFECT LEVEL
0–100 Adjusts the volume of the effect sound.
DIRECT LEVEL
0–100 Adjusts the volume of the direct sound.
