The Amplitude Envelope (AMPENV) Page

Attack segments 2 and 3 aect the sound only when you set a nonzero value for time. ey
will then move to their assigned levels in the time specied. eir starting levels are equal to
the nal levels of the preceding segment.
Decay Segment
e decay section has only one segment. It has values for time and level, just as for the attack
section. e decay section begins as soon as the attack section has been completed. It starts
at the same amplitude level as the attack segment preceding it, and moves to its assigned
level in the time specied. You’ll hear a note’s decay section only when the attack section is
completed before a Note O message is generated for that note.
To create a sustaining envelope, simply set the Decay segment’s level to a nonzero value.
Release Segments
Like the attack and decay sections, each of the three segments in the release section has
values for time and level. Each segment reaches its assigned level in the time specied for
that segment. Release segment 1 starts at the Note O event for each note, at the current
amplitude level of that note—whether it’s in the attack section or the decay section. It then
moves to its assigned level in the time specied. Release segments 2 and 3 start at the nal
levels of the segments before them.
Release segments 1 and 2 can be set to any level from 0 to 150%. Release segment 3
always has a level of 0%, so you can’t adjust its level. In place of its Level parameter you see
a parameter that lets you toggle between User envelopes and the sound’s preprogrammed
natural envelope.
Loop Type
ere are seven dierent values for Loop type.
A value of O disables looping for the current layer’s amplitude envelope.
Values of seg1F, seg2F, and seg3F are forward loops. In each case, the amplitude envelope
plays through the attack and decay sections, then loops back to the beginning of the rst,
second, or third attack segments, respectively.
Values of seg1B, seg2B, and seg3B, are bidirectional loops. e amplitude envelope plays
through the attack and decay sections, then reverses and plays backward to the beginning of
the rst, second, or third attack segment, respectively. When it reaches the beginning of the
assigned attack segment, it reverses again, playing forward to the end of the decay section,
and so on.
Number of Loops
A value of Inf makes the amplitude envelope loop until a Note O is generated. Values of 1
through 31 indicate how many times the loop will repeat after the amplitude envelope has
played once through its normal cycle.
