Repeat: Off, On —When on, the Delay, Attack, and Decay segments of
the envelope repeat. Sustain still affects the level at which the Decay
segment ends, but—instead of sustaining at a fixed level while a note is
gated on—Delay, Attack, and Decay loop until the note is turned off. The
Release segment begins when the note is gated off, just as it does when
Repeat is off. See the illustration on the following page.
