IWAVE/LFO
Offset: Tfiis shifts
the
waveform
of
the
LFO
toward either
(+)
or
{
-
). If it
is
shitted to
the + side
(
-
side), the
center
of the vibration of
the
sound becomes
higher
(bigger)
or lower (smaller)
than the
original pitch or
sound volume. For example, you can
create automatic
trills
by setting the offset of the
square
waveform
to
+100
or
-
100,
and
applying
it
to the pitch with
an
appropriate
depth
setting.
Delay:
This allows
you
set
a
delay so
that
the
LFO
starts
a
certain
time
after
the
key has been
played (key
on).
Fade:
This
determines
the time
change from
when
the
LFO
is first
applied
until
it
reaches
the
depth
that
is
set
by
the
depth
parameter.
Rate: This
determines
the vibration
speed
of
the
LFO.
You
should use delay
when you
don't
want
to
have
the
LFO
to start at the
same
time
as
the
sound
itself starts,
or
when
you want
to simulate the
sound of an
actual
musical instrument
in
which
vibrato
is
usually applied
after
the
sound
starts.
In
such a
case, the
depth of the vibration can be
made
to
gradually increase
by
using the fade
time
settings, letting
you
create natural vibrato
and tremolo
effects.
Also, setting the
rate
to
low
values creates vibrato and
tremolo
effects,
while higher values
create a
vague and
distorted
sound.
Depth:
This determines the
vibration
depth
of the
LFO.
The
way
of changing
the pitch
and sound
volume
are reversed,
when
the
value of depth
is
(+)
and
(
~
).
For
example,
the
phase of
the
modulation
becomes
reversed
when
setting
the
depth
to a
positive value (+) for
one Tone,
and
setting the
same amount
of the depth
on
the
negative
(
-
)
side for
another Tone.
By
using
this
operation,
different
Tones can be sounded
alternately,
and
the
sounds can be
moved
back and
forth
over
the stereo
image
in
combination with
the
pan
function (explained below).
You
can
create a
bell-like effect
if
you
set
the
depth of
the
saw
waveform
of the offset to
100 with
the
(
-
)
value
as the level
and
cutoff.
