Decay/Release
ENV 1 can be set to act as an envelope generator with an Attack time and Decay time
parameter or with an Attack time and Release time parameter.
Switching between both modes is achieved by clicking on the D or the R above the
right ENV 1 slider.
 In its Attack/Decay mode, the level will fall to zero after the attack phase has
completed, no matter whether you sustain the note or not. It will decay at the same
speed even if you release the key. The decay time is set with the Decay time slider,
abbreviated as D.
 In its Attack/Release mode, the envelope level remains at its maximum after the
attack phase is over, as long as the key remains depressed. Following the release of
the key, its level decreases over the time set with the R slider—the abbreviation for
Release time.
Attack Time and Attack Via Vel
The Attack time slider is 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.
You can grab the area between the two slider halves with the mouse and drag both
halves simultaneously. If this area is to small to be grabbed with the mouse, just click in
a free part of the slider track, and move the mouse up or down to move the area.
