AMPLITUDE:
Sensitivity to
amplitude modulation
is
variable
from
to
3.
Amplitude modulation
sensitivity
is
set
independently
tor
each
operator.
Applying amplitude modulation
to a
mod-
ulator creates
"wow"
effects,
while applied
to
a carrier
it
results
in
tremolo
effects.
Operators are selected using the
jOPERATOR
SE-
LECT
|
key. Pressing the
|
OPERATOR
SELECTi
key
successively
selects
the operators
in
order from
1
to
4.
The number
of
the
selected
operator
is
displayed
in
the
upper
right
hand
corner of the display panel.
Operators
that are turned
OFF
will
be "skipped"
and
the
number
of the next active operator
will
be
displayed.
Disabled operator
cannot be
selected

FINE:
The

frequency
of
each
oscillator
is
set
using the

and
IFREQUENCY

keys.
With
a
value of 1.00
as
standard
(8 feet),
the
FREQUENCY
COARSE
control can
be used to
set
the
frequency between
0.5
and 32

The

control
then
permits
fine

SYNC
(Synchronize):
When
the
SYNC
function
is
ON,
all
operators begin
oscilla-
tion
from
the
same phase
angle
{0
degrees).
With
SYNC
OFF
the phase angle
at
which
an operator begins
oscilla-
tion
is
carried
over
smoothly from
the preceding note.
In
the
polyphonic mode,
for
example,
maximum
simultaneous
output
is
16
notes.
If
a
17th key
is
pressed the

The
envelope generator determines
how
the
amplitude
(volume)
or timbre
(tone) of
a
note
will
vary over time.
Envelope modulation
of a modulator
results in
time-based
timbre
variations, while envelope modulation
of
a carrier
produces amplitude
variations.
