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 PITCH B MODE SET button is pressed while turning on the power to the DX100.

19:MODULATION WHEEL RANGE, AMPLITUDE

As you move the DX100 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 MODULATION 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 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 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 DX100 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.

The four BREATH parameters listed below determine just how the breath controller will affect the DX100’s sound. These parameters may be set individually, or combined for more complex effects.
