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 itÕs held on by a pedal, by the IgnRel
parameter (described in the section entitled The LAYER Page on page 6-19), or whatever.
The Envelope 2 (ENV2) and Envelope 3 (ENV3) Pages
The K2600 offers 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 canÕt have an
amplitude less than zero, so AMPENV is unipolarÑthe values range from 0 to 100%.) A bipolar
envelope controlling pitch, for example, could modulate the pitch both above and below its
original level.
Another difference 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 affect the layerÕs amplitude. ENV2 and
ENV3 affect 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 Þnish).

The pages for Envelopes 2 and 3 are reached with the soft buttons ENV2 and ENV3. When you
select these pages, youÕll Þnd a display that looks very much like the AMPENV page. The only
differences are that you can program an amount for Rel3, and in the envelope graphic, which
has a dotted line running horizontally across the display. This is the zero level line; negative
level values for the various envelope segments will cause the envelope graphic to dip below this
line.
