Additional Filter Envelope Parameters (Display Menus)
Additional Filter parameters are accessible through the menus in the
main display. To see these menus, adjust any of the lter envelope controls
in the envelopes section of front panel. The envelope parameters are in
the rst two menu tabs.

Attack: 0...127—Sets the attack time of the envelope. The higher the
setting, the slower the attack time and the longer it takes for a sound to
reach its full volume. Pads typically have softer (longer) attacks. Percus-
sive sounds have sharper (shorter) attacks.
Decay: 0...127—Sets the decay time of the envelope. After a sound
reaches its full volume at its attack stage, decay controls how quickly the
sound transitions to the level set with the sustain control. The higher the
setting, the longer the decay. Percussive sounds, such as synth bass, typi-
cally have shorter decays.
Sustain: 0...127—Sets the sustain level of the envelope. The higher the
setting, the louder the sustained portion of the sound will be. The sound
will stay at this level for as long as a note is held on the keyboard.
Release: 0...127—Sets the release time of the envelope. This controls
how quickly a sound dies out after a note is released.

Env Amount: -127...127—Sets the amount of modulation from the lter
envelope to the lter’s cutoff frequency. Any setting above zero means
that each time you strike a key, the lter envelope controls how the lter
opens and closes. Higher amounts more dramatically affect the cutoff
frequency. This control is bipolar. Positive settings produce standard
behavior. Negative settings invert the envelope.
Velocity On/Off: On, Off—Allows key velocity to inuence lter cutoff
frequency. If on, the harder you play, the more the lter will open and the
brighter the sound will be. If off, key velocity will not affect the lter.
This control allows for more touch-sensitive sounds.
Delay: 0...127—Sets a delay between the time the envelope is triggered
(note on) and when the attack portion actually begins.
Env Repeat: Off, On—When on, the Delay, Attack, and Decay segments
of the envelope repeat. Sustain still affects the level at which the Decay
segment ends, but instead of sustaining at a xed level while a note is
gated on, Delay, Attack, and Decay loop until the note is turned off. The
Release segment begins when the note is gated off, just as it does when
Repeat is off.
