Logic Pro ES2 Envelope1 controls
Although Envelope 1 (ENV1) appears to be simplistic, it is useful for a range of synthesizer
functions.
ES2 Envelope1 parameters
• Trigger Modes pop-up menu: Choose a mode to define the trigger behavior of ENV1.
• Poly: The envelope generator behaves as you would expect on any polyphonic
synthesizer:every voice has its own envelope.
• Mono: A single envelope generator modulates all voices in the same way. All notes
must be released before the envelope can be retriggered. If you play legato, or any
key remains depressed, the envelope does not restart its attack phase.
• Retrig: A single envelope generator modulates all voices in the same way. The
envelope is triggered by any key you strike, even when other notes are sustained. All
sustained notes are identically affected by the retriggered envelope.
• Attack via Velocity slider: The Attack time slider is divided into two halves. Move the
lower slider to set the attack time when keys are struck at maximum velocity. The top
slider sets 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, click an unused
portion of the slider, and drag vertically.
• Decay/Release mode button: Switch ENV 1 between an Attack/Decay or an Attack/
Release envelope. The button label changes to reflect the mode that is activated
(D=Decay, R=Release).
• In Attack/Decay mode: The level falls to zero after the attack phase has completed,
whether or not the note is sustained. It decays at the same speed, even if you
release the key. Set the decay time with the Decay time slider. Define the time
required for the level to decrease to zero with the Release time slider, once the key
is released.
• In Attack/Release mode: The envelope level remains at its maximum after the attack
phase is over, while the key remains depressed.
Logic Pro ES2 Envelope 2 and 3 controls
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.
