LFO
Low
Frequency
Oscillator
parameters
(common
to
all
operators).
The
diagram
below shows
how
LFO
modulation
is
sent; either "automatically"
(AMD
and
PMD)
or regulated
by
a controller (see p.23).
As
you can
see
from
the diagram,
if
the
Sensitivity settings are
0,
the
LFO
will
have no
effect.
Wave
(triangle,
saw
down, saw
up, square,
sine,
s/hold)
Five periodic
wave-shapes and "random"
sample-and-hold.
Speed
(0-99)
Adjusts the
LFO
frequency.
Delay (0-99)
A
time delay can
be
set before the
LFO
begins.
Mode
(single, multi)
In
Single
mode,
the
LFO
begins
when
the
first
key
is
hit
and
con-
tinues with the
same
phase
for
all
subsequent
notes.
(I.e.
the
LFO
effect
is
"synchronized"
for
all
notes.)
In
Multi
mode,
an independent
LFO
begins
when
each
note
is
played.
Thus, each
note can be
at a different phase.
Pmd
(0-99)
Pitch
Modulation Depth
Amd
(0-99)
Amplitude Modulation Depth
Pitch
Modulation Depth and Amplitude Modulation Depth
determine
the
amount
of
LFO
signal sent
directly to
the
voice;
i.e.
"automatic"
as
opposed
to
an
effect regulated
by
a Controller,
etc.
(p.23).
Sync
(off,
on)
LFO
Key Sync
When
Sync
is
on,
each
note
restarts the
LFO
from phase
0.

Pitch
EG
Pitch
Envelope Generator
rates
R1-4
and
levels
L1-4
determine
how
the
pitch
changes
with
time. Level
50
is
the
normal
pitch.
The
difference
in
pitch bet-
ween
levels
of
and 99
can be
set
from
1/2
to
8
octaves.
When
Pitch
EG
Velocity
Sensitivity
is
switched
on, the
intensity
of the
Pitch
EG
effect
wilt
depend on
the key touch.
When
Rate Scaling
is
0,
the envelope
will
be
the
same
speed
for
any note
on
the keyboard.
As
Rate Scaling
is
increased, higher
notes
will
have
faster
envelopes.
