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.

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.

Values are sampled at the interval set using "SPEED" .
Sets the LFO speed.
0 to 127
When "WAVE" is set to "S&H" or "S&H8" , this parameter deter-
mines the interval at which values are sampled.
0 to 127
Sets how long it takes after pressing a key for the LFO to start.
0 to 127
Sets the degree to which the pitch is affected by the LFO (vibrato).
