Roland JV-880 - LFO1, 2 (LFO parameters) LFO waveform

LF01,
2
(LFO
parameters)
LFO is an
abbreviation
for
Low Frequency
Oscillator, and is used to periodically modulate
the pitch
of the Tone,
cutoff
frequency of
the filter, and the volume.
LFO is applied to the
WG, TVF
and TVA
(explained
below) for
creating tremolo,
pitch change, and
other effects.
The JV-880
has two
independent LFOs (LF01
and LF02)
for
each Tone.
* The
parameters
are the
same for both
LF01 and
2.

This parameter lets
you select

of
the LFO. A mark indicating the

is displayed
along
with
the name in the

In
order to add modulation
and
vibrato,
sefect
the sine wave
or triangle wave,
and
apply it in
small
degrees
to the level
(volume)
and
the pitch. The random
waveforms
are
useful in creating special sound
effects
and
modulation.
