ES2 Envelope 2 and 3 in MainStage
The feature sets of ENV 2 and ENV 3 are identical, but it is always the task of ENV 3 to define the level of each note—to modulate the dynamic stage, in other words. ENV2 is preconfigured to control the Cutoff frequency of both filters.
Both ENV 2 and ENV 3 can also be used simultaneously as sources in the router. The envelope time parameters can be used as modulation targets in the router.

ES2 Envelope 2 and 3 parameters
Attack slider: Define the time required for the level of a note to rise from an amplitude of zero to the set amplitude. The Attack time sliders of ENV 2 and ENV 3 are divided into two halves.
The lower half defines the attack time when the keys are struck hard, at maximum velocity. The upper half defines the attack time at minimum velocity.
Drag the area between the two slider halves to move both simultaneously. If this area is too small to drag, drag an unused portion of the slider vertically.
Decay slider: Set the time it takes for the level of a held note to fall to the sustain level, after the attack phase has completed.
If the Sustain level parameter is set to its maximum value, the Decay parameter has no effect.
When the Sustain level is set to its minimum value, the Decay parameter defines the duration or fade-out time of the note.
Sustain/Sustain Time sliders: Set the sustain level and the sustain time. See Use ES2 Envelope 2 and 3 sustain.
Release Time slider: Define the time required for the sustain level to fall to zero, after the key is released.
Velocity Sensitivity slider: Determine the velocity sensitivity of the entire envelope. If set to maximum, the envelope outputs its maximum level only when the keys are struck at maximum velocity. Softer velocities result in a corresponding change to the envelope levels, with a 50% velocity resulting in half-levels for each envelope-level parameter.
