velocity will not affect the volume. This control allows for more touch-
sensitive sounds.

—Sets the attack time of the envelope. The higher the
Attack: 0...127
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.
—Sets the decay time of the envelope. After a sound
Decay: 0...127
reaches its full volume at its attack stage, controls how quickly the
decay
sound transitions to the level set with the control. The higher the
sustain
setting, the longer the decay. Percussive sounds, such as synth bass, typi-
cally have shorter decays.
—Sets the sustain level of the envelope. The higher the
Sustain: 0...127
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.
—Sets the release time of the envelope. This controls
Release: 0...127
how quickly a sound dies out after a note is released.
