To finish programming the partial, touch the LFO tab to change to the
LFO screen.
"LFO" stands for "Low Frequency Oscillator." An LFO produces sound
like a partial does, only it's so low-pitched you can't hear it directly.
Instead, the LFO is applied to other settings, causing them to rise and
fall over and over at the LFO's frequency.
Each partial has two LFOs, and their use is optional. LFOs aren't
devices the partial passes through—rather, they affect the behavior of
the OSC, FILTER, and AMP devices.

MODULATION LFO Controls—These settings control vibrato added
to the partial when you push the VR-09's Pitch Bend/Modulation
lever forward.
Setting This setting:
SHAPE sets the type of wave shape
the lever LFO uses as it
cycles over and over.
TEMPO acts as an on/off switch for
SYNC Tempo Sync, which locks
the lever LFO cycle with the
VR-09's DRUM-area tempo.
RATE sets the rhythmic
relationship between the
lever LFO and the DRUM
tempo when Tempo Sync
is on.
RATE sets how much pushing the
CONTROL lever forward affects the
lever Rate value.
PITCH sets the amount of the lever
DEPTH LFO applied to the partial's
pitch.
Can be set to:
•
—triangle wave
•
—sine wave
•
—sawtooth wave
•
—square wave
•
—sample and
hold—the wave
shape changes with
each cycle.
•
RND (Random)—the
LFO shape changes
randomly constantly.
