ES2 Envelope 2 and 3 in Logic Pro for iPad

The feature sets of Envelope 2 and Envelope 3 are identical, but it is always the task of Envelope 3 to define the level of each note—to modulate the dynamic stage, in other words. Envelope 2 is preconfigured to control the Cutoff frequency of both filters.

Both Envelope 2 and Envelope 3 can also be used simultaneously as sources in Mod Matrix Slots 1–10. The envelope time parameters can be used as modulation targets in Mod Matrix Slots 1–10.

ES2 Envelope 2 and 3 parameters

Attack via Velocity Min/Max sliders: Move the left slider (AtkMaxV) to set the attack time when keys are struck at maximum velocity. The right slider (AtkMinV) sets the attack time at minimum velocity.
Decay slider and field: 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/SusTime sliders and fields: Set the sustain level and the sustain time. See Use ES2 Envelope 2 and 3 sustain.
Release slider and field: Define the time required for the sustain level to fall to zero, after the key is released.
Velocity Sens knob and field: 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.
