1 Filter/EG
• 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.

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

Cutoff Determines the cutoff frequency or
effective frequency range of the filter
(see diagram). Higher values result in a
brighter sound.
Resonance Determines the emphasis given to the
cutoff frequency (resonance), set in
BRIGHT. above (see diagram). 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.
Decay Determines how quickly the sound reaches its sustain level (a slightly lower level
than maximum). The lower the value, the quicker the decay.
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.
Speed Determines the speed of the Vibrato effect.
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.
