MODULATION
The [MODULATION] wheel can be used to modulate the parameters below as well as the pitch (vibrato).
Here, you can set the degree to which the [MODULATION] wheel modulates each of the following
parameters.

 SOUND Page
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 frequency range. In addition to making the sound either brighter or mellower, Filter can be used to
produce electronic, synthesizer-like effects.

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