Attack Segment Times
These indicate how long it takes for the current layerÕs amplitude to reach its Þnal level from its
starting level.
Attack Segment Levels
These are the Þnal levels that each segment achieves at completion. The levels are expressed as
percentages of the maximum possible amplitude for the current layer. Attack segment 1 always
starts at zero amplitude, and moves to its assigned level in the time speciÞed by its time value.
So the default settings of 0 seconds and 100% mean that the Þrst segment of the attack section
moves instantly from zero amplitude to 100% amplitude. Increase the time of Attack segment 1
if you want the sound to ramp up more slowly.
Attack segments 2 and 3 affect the sound only when you set a nonzero value for time. They will
then move to their assigned levels in the time speciÞed. Their starting levels are equal to the
Þnal levels of the preceding segment.
Decay Segment
The decay section has only one segment. It has values for time and level, just as for the attack
section. The 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 speciÞed. YouÕll hear a noteÕs decay section only when the attack section is completed
before a Note Off message is generated for that note.
To create a sustaining envelope, simply set the Decay segmentÕs 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 speciÞed for that segment.
Release segment 1 starts at the Note Off event for each note, at the current amplitude level of
that noteÑwhether itÕs in the attack section or the decay section. It then moves to its assigned
level in the time speciÞed. Release segments 2 and 3 start at the Þnal levels of the segments
before them. Release segments 1 and 2 can be set to any level from 0 to 100%. Release segment 3
always has a level of 0%, so you canÕt adjust its level. In place of its Level parameter you see a
parameter that lets you toggle between User envelopes and the soundÕs preprogrammed natural
envelope.
Loop Type
There are seven different values for Loop type.
A value of Off disables looping for the current layerÕs 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 Þrst, second, or
third attack segments, respectively.
Values of seg1B, seg2B, and seg3B, are bidirectional loops. The amplitude envelope plays
through the attack and decay sections, then reverses and plays backward to the beginning of the
Þrst, 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.
