The
LFO
modulation can be
made
to
modulate
the pitch of the
voice, producing
a
range
of vibrato
type
effects.
The
WHEEL
RANGE,
PITCH
function
is
used
to
set
the
maximum
depth
of pitch modulation
which
can be
applied using the
Mo-
dulation
Wheel. The
actual
effect
produced depends on
the
settings of the
LFO
parameters
(these
will
be discussed
in
CHAPTER
IV:
VOICE PROGRAMMING).
Note,
however,
that the appropriate voice PITCH
MODULATION
SENSITIVITY
parameter
must
be
set to a value higher than
for pitch
modulation
to
be
effective.
(The
voice
PITCH
MODULATION
SENSITIVITY
parameter
will also
be discussed
in
CHAPTER
IV.

The
data range
is
from
to 99.
At
0,
pitch
modulation
is
OFF,
and moving
the Modulation Wheel
will
cause no
pitch
modulation
to
be
applied
to
the
voice.
A
setting of
99
will
produce
the
greatest possible pitch
modulation
depth.
Data
is
entered using the
DATA ENTRY
slider or buttons.
Once
this
function
is
called,
subsequent
presses
of button
#18
will
increment
the data value.
NOTE:

I
Modulation Wheel

is

to the

MODULATION WHEEL
RANGE, AMPLITUDE
The
LFO modu
lation
can
also be
made
to
modulate
the amplitude
(level)
of specified
voice elements
(operators),
producing
a
range
of tremolo
or timbre modulation
(wah-wah)
type
effects.
The
WHEEL
RANGE,
AMPLITUDE
function
is
used
to
set
the
maximum
depth
of
amplitude modulation
that can be
applied
by
using the
Modulation Wheel. The
actual effect
produced depends on
the settings of the
LFO
parameters (discussed
in
CHAPTER
IV:
VOICE PROGRAMMING).
The
appro-
priate voice
AMPLITUDE MODULATION
SENSITIVITY
parameter must be
set to
a
value higher than
for
amplitude modulation
to
be
effective.
(The
voice
AM-
PLITUDE
MODULATION
SENSITIVITY
parameter
will
also
be
discussed
in
CHAPTER
IV.)
The
data range
is
from
to 99.
At
0,
amplitude modulation
is
OFF, and moving
the Modulation Wheel
will
cause no amplitude modulation
to
be
applied
to
the
voice.
A
setting of
99
produces
the greatest possible
amplitude modulation
depth.
Data
is
entered using the
DATA ENTRY
slider or buttons.
Once
this
function
is
called,
subsequent
presses
of
button #19
will
increment
the data
value.
The
Yamaha
Breath
Controller
The
optional
Yamaha
BC-1
Breath Controller
is
a
unique
way
of
adding
musical
expression
as
you
play the
DX1 00
keyboard. The BC-1
is
held
in
the
mouth
just
like
the
mouthpiece
of a
wind
instrument.
Blowing
harder
or softer into the
BC-1
mouthpiece produces
a
corresponding
effect.
The
Breath Controller
can be used
to
apply varying
amounts
of pitch or amplitude
LFO
modulation,
just
like
the
Modulation Wheel.
In
addition,
it
can be
set
up
to directly affect
the
pitch,
amplitude
or timbre
in
response
to
breath pressure.
When
used
to directly affect amplitude
(EG
BIAS),
for
example,
the Breath Controller
can be used
to
add
realistic
tonguing
effects to
brass and
other
wind
instrument sounds.
The
four
BREATH
parameters
listed
below
determine
just
how
the Breath Controller
will affect
the
DX1
00's sound. These parameters may
be
set individually, or
com-
bined
for
more complex
effects.
