I SOUND
G 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 more mellow, Filter can be used
to produce electronic, synthesizer-like effects.
BRIGHTNESS
HARMONIC CONTENT
G EG (Envelope Generator)
The EG (Envelope Generator) settings determine how the level of the sound changes in time. This lets you
reproduce many sound characteristics of natural acoustic instruments — such as the quick attack and decay
of percussion sounds, or the long release of a sustained piano tone.

I EFFECT/EQ
Same as in "Organ Flutes" on page 84, with the exception of the PANEL SUSTAIN parameter, which
determines the sustain level applied to the edited voice when turning the [SUSTAIN] button in the
VOICE EFFECT section on.
I HARMONY
Same as in the [FUNCTION] → HARMONY/ECHO display. See page 154.
Determines the cutoff frequency or effective frequency range of the filter (see diagram).
Higher values result in a brighter sound.
Determines the emphasis given to the cutoff frequency (resonance), set in BRIGHTNESS
above (see diagram). Higher values result in a more pronounced effect.

These frequencies are Cutoff range
"passed" by the filter.
Determines how quickly the sound reaches its maximum level after the key is played. The
higher the value, the slower the attack.
Determines how quickly the sound reaches its sustain level (a slightly lower level than max-
imum). The higher the value, the slower the decay.
Determines how quickly the sound decays to silence after the key is released. The higher
the value, the slower the release.

Determines the intensity of the Vibrato effect (see diagram). Higher settings result in a more
pronounced Vibrato.
Determines the speed of the Vibrato effect (see diagram).
Determines the amount of time that elapses between the playing of a key and the start of
the Vibrato effect (see diagram). Higher settings increase the delay of the Vibrato onset.
