Modulation Sensitivity Parameters
The Modulation Sensitivity parameters (Pitch and Amplitude) determine the degree
to which LFO modulation affects the voice — in other words, the intensity of the
LFO effect. Modulation Sensitivity is effectively a master control for all modulation
— whether it is automatically applied when the notes are played, or whether it is
applied only by using the "real time" modulation controls on the MIDI keyboard,
such as the Modulation Wheel, Foot Control, Breath Control or After Touch. If the
Pitch or Amplitude Modulation sensitivity is set at zero, then none of the external
controllers can affect the voices.
• Pitch Modulation Sensitivity
Range: 0 ... 7
This determines sensitivity of the voice (all operators) to LFO pitch modulation. Higher
values result in greater sensitivity, or greater intensity of pitch modulation. This parame-
ter setting affects all operators of the voice equally.
• Amplitude Modulation Sensitivity
Range: 0 ... 7
This determines sensitivity of each operator to LFO amplitude (volume) modulation.
Higher values result in greater sensitivity, or greater intensity of volume modulation.
