FEEDBACK:
One
operator
in
each
of the
8 algorithms has
its
output
fed
back
to
its
input.
This
is
the
f.eedbacl<
operator.
The
amount
of feedbacl< applied
can be
adjusted over
a
range
of to
7.
By
increasing the
FEEDBACK
level
the
harmon-
ics
are increased,
resulting
in
the generation of
noise-like
sounds.

The
Low
Frequency
Oscillator
produces low-frequency
sine,
saw-tooth
or square waves, or
a
SAMPLE/HOLD
waveform.
The LFO
waveform
can be used to apply
vibrato,
tremolo
or
"wow"
effects to the
voices.
The amount
of
LFO
modulation
applied
can be
controlled using the
modulation
wheel, or breath controller
once
appropriate
WAVE, SPEED
and
DELAY
parameters
are
set.
(Refer to

WAVE:
This
selects

output by the
LFO.
Any

DELAY:
This
creates a
delay
between

and
ap-
plication of
LFO
modulation.
A
setting of

in
no
delay
- LFO

a setting of

PMD
(Pitch
Modulation Depth):
Varies,
over
a to
99
range,
the depth
of
LFO
modulation
applied to
pitch.
A
setting
produces
no
pitch
modulation,
and
a setting of
99 produces
maximum
modulation.
The
PMD
function
is
separate
from
the effect of the con-
trollers,
and
can be used
to
apply
vibrato effects that are
entirely
independent
of the controller
settings.
AMD
(Amplitude Modulation Depth):
Varies,
over
a to
99
range, the
depth
of
LFO
modula-
tion applied to amplitude.
A
setting
produces
no
ampli-
tude modulation, and
a setting of
99
produces
maximum
modulation.
The
AMD
function
is
separate
from
the
effect
of the con-
trollers,
and can be used to apply tremolo
effects
that are
entirely
independent
of
the

settings.
