you see a parameter that lets you toggle between User envelopes and the sound's
preprogrammed "natural" envelope.
Loop Type
There are seven different values for Loop type.
A value of Off 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 first, 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 first, 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 Off 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 off (that is, when a Note Off 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"), or whatever.
