Attack
Knob 3
This value sets the rate at which the pitch moves from its initial level (at Note On) to the
attack level. Higher values produce faster rates.
Decay
Knob 4
This value sets the rate at which the pitch moves from the attack level to the sustain
level. Higher values produce faster rates.
Release
Knob 5
This value sets the rate at which the pitch moves from the sustain level to the release
level following Note Off. Higher values produce faster rates.
Note that the effectiveness of this setting declines at higher AEG release rates ( 189),
since the sound dies out before the shift in pitch can be heard.
