Modulation (+), A controller to which this function is assigned can be used to modulate the parameters below as well as the pitch
Modulation (-) (vibrato). Here, you can set the degree to which the controller modulates each of the following parameters.

NOTE
LFO (Low Frequency Oscillator) is a device which periodically varies (oscillates) a signal by using a low frequency wave. For example, a vibrato effect can be produced by
applying LFO to the pitch, a wah effect can be produced by applying it to the filter, and a tremolo effect can be produced by applying it to the volume of a Voice.
Sound
Filter Filter is a processor that changes the timbre or tone of a sound by either blocking or passing a specific frequency
range. The parameters below determine the overall timbre of the sound by boosting or cutting a certain fre-
quency range. In addition to making the sound either brighter or mellower, Filter can be used to produce elec-
tronic, synthesizer-like effects.

Determines the degree to which the joystick modulates the Filter Cutoff Frequency. For
details about the filter, see below.
Determines the degree to which the joystick modulates the amplitude (volume).
Determines the degree to which the joystick modulates the pitch, or the vibrato effect.
Determines the degree to which the joystick modulates the Filter modulation, or the wah
effect.
Determines the degree to which the joystick modulates the amplitude, or the tremolo effect.
Determines the cutoff frequency or effective fre-
quency range of the filter (see diagram). Higher
values result in a brighter sound.
Determines the emphasis given to the cutoff fre-
quency (resonance), set in Cutoff above (see dia-
gram). Higher values result in a more
pronounced effect.
