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.
EG
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.
VIBRATO
Vibrato is a quavering, vibrating sound effect that is produced by
regularly modulating the pitch of the Voice.

BRIGHT.
(Brightness)
Determines the cutoff frequency or
effective frequency range of the fil-
ter (see diagram). Higher values
result in a brighter sound.

HARMO.
(Harmonic con-
tent)
Determines the emphasis given to
the cutoff frequency (resonance),
set in BRIGHT. above (see dia-
gram). Higher values result in a
more pronounced effect.

ATTACK
Determines how quickly the sound reaches its maximum level after the
key is played. The lower the value, the quicker the attack.
[4

]
DECAY
Determines how quickly the sound reaches its sustain level (a slightly
lower level than maximum). The lower the value, the quicker the decay.
[5

RELES.
(Release)
Determines how quickly the sound decays to silence after the key is
released. The lower the value, the quicker the decay.

DEPTH
Determines the intensity of the Vibrato effect. Higher settings result in a
more pronounced Vibrato.
[7

]
SPEED
Determines the speed of the Vibrato effect.
[8

]
DELAY
Determines the amount of time that elapses between the playing of a key
and the start of the Vibrato effect. Higher settings increase the delay of
the Vibrato onset.
Volume
These frequencies are
“passed” by the filter.
