Although Envelope 1 (ENV 1) appears to be simplistic, it is useful for a range of synthesizer functions.
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.
