Parameters Assigned to the Knobs
This section describes each of the parameters which can be assigned to the Knobs (page 25).
z
Filter
Filter effects shape the sound by allowing only a
specified range of frequencies to pass and/or by pro-
ducing a resonance peak at the filter’s “cutoff” fre-
quency. Filter effects can be used to create a range of
synthesizer-like sounds.
specified range of frequencies to pass and/or by pro-
ducing a resonance peak at the filter’s “cutoff” fre-
quency. Filter effects can be used to create a range of
synthesizer-like sounds.
Knob A: CUTOFF
Adjusts the filter’s cutoff frequency, and therefore the
brightness of the sound. Turning the knob to the left
makes the sound more muffled or darker, while turn-
ing the knob A to the right makes the sound brighter.
brightness of the sound. Turning the knob to the left

Knob B: RESONANCE
Adjusts the amount of Resonance applied at the fil-
ter’s cutoff frequency. Turning the knob to the right will
increases the Resonance to emphasize the frequen-
cies at the cutoff frequency, and thus “strengthens”
the perceived effect of the filter.

Effect
Knob A: REVERB
Reproduces the acoustic ambience of a concert hall
or club. Turning the knob to the right increases the
Reverb depth.

Reverb depth.
Knob B: CHORUS
Produces a layered “multi-instrument” effect. Turning
the knob to the right increases the Chorus depth.

EG (Envelope Generator)
Envelope Generator effects determine how the level
of the sound varies over time. You can make the
attack faster for a more percussive sound or slower
for a violin-like sound, for example. Or you can
lengthen or shorten the sustain to best match the
music you’re playing.

attack faster for a more percussive sound or slower
for a violin-like sound, for example. Or you can
lengthen or shorten the sustain to best match the
music you’re playing.
Knob A: ATTACK
Adjusts the Attack Time (the amount of time it takes
the sound to reach maximum level when a key is
played). Turning the knob to the right increases the
Attack Time, thus slowing down the attack rate.

Knob B: RELEASE
Adjusts the Release Time (the amount of time it
takes for the sound to decay to silence after a key is
released). Turning the knob to the right increases the
Release Time, thus making a longer sustain.

Style Filter
Same as

. These effects are applied only to Style
or Pattern playback.
b
Volume Balance/Pattern Retrigger
Knob A: VOLUME BALANCE
Adjusts the volume balance between the audio play-
back volume from the connected audio device (page
36) or the computer (page 36) and the Song/Style/
Pattern. Turning the knob to the left decreases the
external audio volume, while turning it to the right
decreases the instrument volume.

• Filter effects can sometimes cause distortion in the bass fre-
quencies.
