Setting the LFO

You can set the LFO (low frequency oscillator) to change the waveform used to vary the sound and 
apply effects such as vibrato, tremolo, and wah. 

1.

Press the [EDIT] button to activate Edit mode.

2.

Press the [LFO] button.
The LFO Settings screen is displayed.

3.

If necessary, press the [LFO] button several times to switch between this screen’s pages.

4.

Adjust the LFO by using the sliders and/or switches.

5.

When you have finished making settings, press the [EDIT] button once again to leave Edit mode.

WAVE

Selects the LFO waveform.

SIN

Sine wave

TRI

Triangular wave

SAW U

Ramp-up type sawtooth wave

SAW D

Ramp-down type sawtooth wave

SQ

Square wave

S&H8

Sample & Hold 8 wave
Values are sampled each 1/8th of the interval set using “SPEED”.

S&H

Sample & Hold wave
Values are sampled at the interval set using “SPEED”.

2

SPEED

0 to 127

Sets the LFO speed.
When “WAVE” is set to “S&H” or “S&H8”, this parameter deter-
mines the interval at which values are sampled.

3

DELAY

0 to 127

Sets how long it takes after pressing a key for the LFO to start.

4

PMD 
(pitch modulation depth)

0 to 127

Sets the degree to which the pitch is affected by the LFO (vibrato).

Sample & Hold (S&H)

Sample & Hold waves are formed by taking (sampling) 
a value from a noise wave at a certain time and keeping 
(holding) that value until the next one is taken. In this 
way, it is possible to create a wave that changes in a 
random fashion.
