As you move the DX27 modulation wheel away from you, an increasing amount
of LFO (Low Frequency Oscillator) modulation is applied to the selected voice.
LFO modulation can be made to modulate the pitch of the voice, producing a range
of vibrato type effects. This function is used to set the maximum depth of pitch
modulation which can be applied using the modulation 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 0 for pitch modulation to be effective. The voice PITCH MODULATION
SENSITIVITY parameter will also be discussed in
CHAPTER
IV.
The data range
is from 0 to 99. At 0, pitch modulation is OFF, and rotating the modulation wheel
will cause no pitch modulation to be applied to the voice. A setting of 99 produces
the greatest possible pitch modulation depth.
Data is entered using the DATA ENTRY slider or buttons. Once this function is
called, subsequent presses on the 18 button will increment the data value.
NOTE:
Modulation Wheel control direction is reversed simultaneously along with the
Pitch Bend Wheel when the PB MODE SET button is pressed while turning
on the power to the DX27.
19: MODULATION WHEEL RANGE, AMPLITUDE
As you move the DX27 modulation wheel away from you, an increasing amount
of LFO modulation is applied to the selected voice. LFO modulation can be made
to modulate the amplitude (level) of specified voice elements (operators), producing
a range of tremolo or timbre modulation (wah-wah) type effects. This function
is used to set the maximum depth of amplitude modulation that can be applied
using the modulation wheel. The actual effect produced depends on the settings
of the LFO parameters, these will be discussed in
CHAPTER
IV:
VOICE PRO-
GRAMMING. Note, however, that the appropriate voice AMPLITUDE MODU-
LATION SENSITIVITY parameter must be set to a value higher than 0 for amplitude
modulation to be effective. The voice AMPLITUDE MODULATION SENSITIVITY
parameter will also be discussed in
CHAPTER IV.
The data range is from 0 to 99. At 0, amplitude modulation is OFF, and rotating
the modulation wheel will cause no amplitude modulation to be applied to thevoice.
A setting of 99 produces the greatest possible pitch modulation depth.
Data is entered using the DATA ENTRY slider or buttons. Once this function is
called, subsequent presses on the 19 button 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 DX27 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 pitch, amplitude
or timbre in response to breath pressure. Set to directly affect amplitude (EG BIAS),
for example, the breath controller can be used to apply realistic tonguing effects
to brass and other wind instrument sounds.
