The four BREATH parameters listed below determine just how the breath controller will affect the DX27’s sound. These parameters may be set individually, or combined for more complex effects.

20: BREATH RANGE, PITCH

This function is used to set the maximum depth of LFO pitch modulation that can be applied using the breath controller. 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 be discussed in CHAPTER IV: VOICE PROGRAMMING.

The data range is from 0 to 99. At 0, pitch modulation is OFF, and applying breath pressure to the breath controller 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 sliderand -1/+1 buttons. Once this function is called, subsequent presses on the 20 button will increment the data value.

21:BREATH RANGE, AMPLITUDE

This function is used to set the maximum depth of LFO amplitude modulation that can be applied using the breath controller. 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 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 be discussed in CHAPTER IV: VOICE PROGRAM- MING.

The data range is from 0 to 99. At 0, amplitude modulation is OFF, and applying breath pressure to the breath controller 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 -1/+1 buttons. Once this function is called, subsequent presses on the 21 button will increment the data value.

22: BREATH RANGE, PITCH BIAS

This function permits breath pressure applied to the BC-1 breath controller to directly control the pitch of the voice. In other words, the LFO has no effect. Only your breath pressure directly affects the pitch of the voice.

The data range is from 0 to 99. At 50, pitch bias is OFF. A setting of 99 permits a 4-octave pitch increase, and a setting of 0 permits a 4-octave pitch decrease to be produced through the breath controller.

Data is entered using the DATA ENTRY slider and -1/+1 buttons. Once this function is called, subsequent presses on the 22 button increment the data value.
