4) Determining the CARRIER FREQUENCY
When
attempting to create
the
sound of a clarinet, the
CARRIER versus MODULATOR
frequency
ratio
should
be set to
1
2.
Press the
I
FREQUENCY FINE
I
and
I
FREQUENCY COARSE
I
keys, and set the pitch to
1.00.
5) Determining the amount of DETUNE.
In
our attempt to
create the
sound of a clarinet, on ly
OPERATOR
1
wi ll be functioning as a carrier and
therefore DETUNE shou
ld
be set to 0.
Press the
ID
E-
TUNE
I key
.
Set
the va lue
of "OSC DETUN
E"
to
0.
6) Setting the ENVELOPE GENERATOR
First, we'
ll
set the ENVELOPE GENERATOR
of the
carrier
.
For examp le, we'
ll
set
the parameters
to the
fol lowing values:
Pressing
each
key
in succession wi
ll
cause
the
values to
advance from
1
to
4.

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 carr ier for an appropriate sound.
Next,
we'll set
up
the modulator data.
7) Using the modulator
In this attempt
to
create the sound of a clarinet,
OPE-
RATOR
2 wil
l
be
functioning
as the so le modulator.
Press
theiO
PER
A
T
OR
21
key. OPE RATOR
2
is now
engaged.
8) Setting the MODULATOR FREQUENCY
Set the
MODULATOR FRE
QUENCY to 2.00
using
the
I FREQUENCY COARSE
I
and I
FREQUENCY FINE I
keys. Set the
DETUNE
for
OPERATOR
2 to 0. Set the
"OSC DETUNE" to 0 using the IDETUNE I
key
.

9) Setting the MODULATOR ENVELOPE GENERATOR
To create
the
sound of a clarinet, the parameters of the
modu
lator
's envelope generator shou
ld
be
identical
to
the parameters
of the carrier's envelope generator. This
process can be carr ied out
in
a
few
seconds
by using
the
COPY
function.
Using the COPY function, copy the
OPERATOR
1
envelope generator
data
to
OPERATOR
2. Set
the
display to "OP
1"
by pressing the I OPERA-
TOR SELECT!
key
.
While
pressing the
r: : I S c=: T : - : : O c-: : R =--=E=-1
key, press
this
key.
The
display
will show the number of
the
operator that was
selected
with
theiOPERATOR
SELECT!
key
.
This
signifies
that
the envelope generator parameters and
keyboard
scaling parameters of
OPERATOR
1
are being
copied to
OPERATOR
2.

At this
point, listen
to the sound
. Th
e sound produced
w
ill
probably be a
little harsh.
In
this
case, lower
the
OUTPUT LEVEL of OPERATOR 2 by pressing on
the
!OPERATO

While
pressing
on
the
OPERATOR
I
OUTPUT

l
key,
lower
the
value of the output
level using
the
DATA ENTRY slid
e
control. With an output
level
setting of 61, the
sound
produced wil
l
approach that of an actual
clarinet. Let's
set the output leve
l
of OPERATOR 2 to 61. Later
on,
with more carefu
I control
of the envelope generators
of
OPERATORS
1
and 2, you
can
tailor the
sound more
precisely for your requirements.
11)
Adding Modulation
Let's
add a vibrato effect to the
clarinet
sound produced.
Set
the
modulation
contro
ls
so that the MODULATION
whee
l
can be used to add
a subtle
touch of vibrato.
1.
Set the
LFO
Waveform.
Pressing the I LFO
WAVE I
key,
set the
wave
form to
"TR lANG
LE".
2. Set the
LFO
Speed.
Pressing the I SPEED I
key, set the
LFO's
speed to "28".
This
wil
l
produce a moderate ly slow vibrato
.
