The Envelope 2 (ENV2) and Envelope 3 (ENV3) Pages
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
There 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. The 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.
Regardless of the loop type and the number of loops, each note goes into its release section as
soon as its Note State goes o (that is, when a Note O is generated). The envelope will continue
to loop as long as Note State remains on, whether it’s held on by a pedal, by the IgnRel parameter
(described in the section entitled The LAYER Page on page 6-17), or anything else.
The Envelope 2 (ENV2) and Envelope 3 (ENV3) Pages
The PC3A oers two envelopes in addition to AMPENV. Like AMPENV, ENV2 and ENV3 can be
assigned like any other control source. Unlike AMPENV, however, ENV2 and ENV3 can be
bipolar. This means that you can set negative values for them. (Obviously, you can’t have an
amplitude less than zero, so AMPENV is unipolar—the values range from either 0 to 100% or 0
to 150%.) A bipolar envelope controlling pitch, for example, could modulate the pitch both above
and below its original level.
Another dierence is that AMPENV always controls the amplitude of the layer, so even if you use
it as a control source for other functions, it will still aect the layer’s amplitude. ENV2 and ENV3
aect only those layers that have them assigned as a control source. Also, AMPENV uses an
exponential attack (the amplitude rises much faster at the end of the attack segment than it does
at the beginning), while ENV2 and ENV3 use linear attacks (the attack segment increases at the
same rate from start to nish).
