AMPLITUDE KEY ON AND KEY OFF ENVELOPES
The Key On Envelope is a 10 segment curve
(maximum) that represents the variation of the
sound's volume for the entire duration that the
notes are held pressed.
The Amplitude Key Off Envelope is a 10 segment
curve (maximum) that represents the variation of
the sound after the notes have been released.
This envelope phase is often called Release.
Examples of a Key On and a Key Off Amplitude
Envelope are shown below.
ZOOM (F7)
Using the ZOOM option, you can enlarge the field
of vision of the envelope up to 4 times at a se-
lected Point.
Pressing the soft button repeatedly selects the
Zoom options in cyclic order (1, 2, 3, 4, 0). Zoom
0 corresponds to "actual size".
SEGMENT (F6)
The SEGMENT option, common to both Key On
and Key Off Envelopes, allows you to divide the
Envelope into several different segments to cre-
ate some interesting Key On and Key Off effects.
A Loop feature is also available.
Edit Sound - Ampl. Envelope showing segment 4 set to Loop. In
practice, the Sound's volume starts at 0, proceeds to the first peak
of segment 1 (attack phase), drops to the lowest point of segment
2, rises to the second peak of segment 3, drops again to the lowest
point of segment 4 then loops back to the highest peak of segment
3 and repeats continually until the key is released.

Add Segm: Inserts a new segment immediately
after the currently selected segment. A maximum
of up to 10 segments is permitted.
Del Segm: Cancels the current segment.
IMPORTANT:
The Key On Envelope must have at least one
segment, (the Attack phase), which cannot
be cancelled.
Loop Segm: Loops the current segment (enve-
lope repetition), provided that the Envelope Fin-
ish parameter in the Envelope control page is set
to "OFF". When it reaches the terminal point, it
loops back to the beginning. The cycle repeats
continually until key release. The initial Loop point
is represented by an arrow [
To eliminate the loop, select the segment and
select "Del Segm.".
SEGMENT, TIME, LEVEL
The Key On and Key Off Envelopes can be de-
fined using the 3 display parameters, Segment,
Time and Level.
