5. LFO
You use the LFO function to set up the sample’s LFO (low-
frequency oscillator). The LFO applies a low-frequency mod-
ulation to the output volume, filter cutoff frequency, and
pitch.
• The [COMMAND/EXIT] button gives you rapid access to a number
of helpful commands while you are working with this function. For
example, you can use the [COMMAND/EXIT] button when you
want to save your edit results to disk, or when you want to cancel
your new changes and restore the previously saved data.
Press the [EDIT] button and then the [F5] button to go to the
LFO functions.
1 display page is provided: LFO.
• See the "Basic Operation" section on page 78 for details on switch-
ing between display pages.

LFO Wave
This parameter selects the LFO waveform. The waveform, in
turn, determines the type of modulation (oscillation) applied
to the sample’s filter, pitch, and amplitude.

Knob 3
[
Turn] LFO Speed
This value sets the modulation speed for the saw, trian-
gle, or square waveform. Higher values produce faster
modulation.
[Range] 1 — 128
•
Modulation speed for the S/H waveform must be set
at the program side (page 107). If you have selected
the S/H waveform (knob2), the screen displays the
current program-side setting. You cannot change the
setting from this page.

Calls the quick entry menu (page 83).
Knob 4
[
Turn] LFO Delay
This parameter sets the interval between Note On and
the onset of LFO modulation. Higher values produce
longer delay together with a more gradual buildup of the
modulation level.
