Applying various effects to the sound
Quick Start
■
Vibrato and Wah effects (LFO)
The LFO, short for “low frequency oscillator,” makes changes to the sound in
periodic fashion. Changing the pitch with the LFO produces the “
vibrato effect ,”
and by changing the filter cutoff frequency with the LFO, you get what is called the
“
wah effect .”

1. Press the patch modify select button to make the BALANCE/LFO indicator
light.
2. Make sure that [FILTER LFO] is off (unlit).
When [FILTER LFO] is off, the two LFO knobs will adjust the vibrato effect.
3. Turn the [LFO DEPTH] knob.
Turning this to the right (clockwise) increases the depth of the undulating sound,
while turning it to the left (counterclockwise) makes the undulation shallower and
milder.
4. Turn the [LFO RATE] knob.
Turning this to the right (clockwise) increases the speed of the undulating sound,
while turning it to the left (counterclockwise) slows the undulation down.
5. Press [FILTER LFO] so it is lit.
When [FILTER LFO] is on, the two LFO knobs will adjust the wah effect.
6. Turn the [LFO DEPTH] knob.
Turning this to the right (clockwise) increases the depth of the undulating sound,
while turning it to the left (counterclockwise) makes the undulation shallower and
milder.
7. Turn the [LFO RATE] knob.
Turning this to the right (clockwise) increases the speed of the undulating sound,
while turning it to the left (counterclockwise) slows the undulation down.

If it is on (lit), press
[FILTER LFO] once again
so it goes out.
[FILTER LFO] does not
take effect on a rhythm set.
