29 Prophet Rev2 User’s Guide Auxiliary Envelope
To create a program in which velocity controls modulation amount, turn
aux
envelope amount
down and turn
velocity amount
up.
Delay: 0...127
—Sets a delay between the time the envelope is triggered
(note on) and when the attack portion actually begins.
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.
