be
set
to 1:2. Press

5)
Determining
the
amount
of
DETUNE.
In
our attempt
to create
the sound of
a clarinet,
only
OPERATOR
1
will
be functioning
as a carrier
and
therefore
DETUNE
should be
set
to
0.
Press
the
|
DE-
TUNE]
key. Set
the value of
"OSC
DETUNE"
to
0.
6)
Setting the
ENVELOPE
GENERATOR
First, we'll
set
the
ENVELOPE GENERATOR
of the
carrier.
For example,
we'll set
the parameters
to
the
following
values:
Pressing
each key
in
succession
will
cause the values to
advance from
1
to
4.

9)
Setting the
MODULATOR ENVELOPE GENERATOR
To
create the
sound
of a clarinet,
the parameters of the
modulator's envelope generator should be
identical to
the parameters of the
carrier's
envelope
generator. This
process can
be
carried out
in
a
few seconds by
using
the
COPY
function. Using the
COPY
function,
copy
the
OPERATOR
1
envelope generator data to
OP
ERATOR
2.
Set the display to
"OP 1"
by
pressing
the
[OPERA-
TOR
SELECT]
key.
While
pressing
the
[STORE
|
key,
press this key.
The
display
will
show
the
number
of the operator
that
was
selected
with the
[QPERATOR
SELECT[
key. This
signifies
that
the envelope generator parameters and
keyboard
scaling
parameters
of
OPERATOR
1
are being
copied
to
OPERATOR
2.

Pressing each key
in
succession
With
the
DX9
set
in
this
mode,
play
on the
keyboard
and
listen
to the
sound produced.
The sound produced
will
be
a
pure
sine
wave from
the
carrier
only.
Now
set
the envelope of the
carrier
for
an appropriate sound.
Next,
we'll set
up
the
modulator
data.
10)
Adjusting
Tone
At
this
point,
listen to
the sound.
The
sound produced
will
probably be
a little
harsh.
In
this case,
lower the
OUTPUT
LEVEL
of
OPERATOR
2 by
pressing
on
the
[OPERATOR
SELECT]
key.
Wh
ile
pressing
on
the
OPERATOR [OUTPUT
LEVEL!
key, lower the
value of the output
level
using
the
DATA ENTRY
slide
control.
With an output
level setting
of 61, the
sound
produced
will
approach
that of
an
actual clarinet. Let's
set
the output
level
of
OPERATOR
2 to 61. Later
on,
with
more
careful
control of the envelope generators of
OPERATORS
1
and
2,
you
can
tailor
the
sound more
precisely for
your
requirements.
7)
Using the
modulator
In
this
attempt
to create
the
sound
of
a clarinet,
OPE-
RATOR
2
will
be functioning
as
the
sole
modulator.
Press the
[OPERATOR
2[
key.
OPERATOR
2
is
now
engaged.
8)
Setting the
MODULATOR FREQUENCY
Set the
MODULATOR
FR
EQUE NCY
to
2.00
using
the
i
FREQUENCY
COARSEI
and
[
FREQUENCY
FINEJ
keys. Set the
DETUNE
for
OPE
RATOR
2 to
0.
Set the
"OSC
DETUNE"
to
using the
[DETUNE
j
key.
11)
Adding Modulation
Let's
add
a
vibrato effect to
the
clarinet
sound produced.
Set the
modulation controls so that the
MODULATION
wheel can be used to add
a
subtle
touch of vibrato.
1.
Set the
LFO
Waveform.
Pressing
the
|
LFO
WAVE
j
key, set
the
wave form
to
"TRIANGLE".
2.
Set the
LFO
Speed.
Pressing
the
[SPEED
[
key,
set
the
LFO's speed
to
"28".
This
will
produce
a
moderately slow
vibrato.
