The Envelope Control (ENVCTL) Page
Envelopes are control sources with outputs that evolve over time without repeating (unless you
want them to). You can make the envelopes even more powerful by using envelope control. This
gives you realtime control over the rates of each section of the envelopes. Press the ENVCTL
soft button to reach the ENVCTL page.

The displayÕs top line reminds you of the current layer. The Þrst line of text in the center of the
display shows Þve of the common DSP control parameters: Adjust, Key tracking, Velocity
tracking, and Source/Depth.
This page is a table showing the Þve envelope control parameters, and their values for each of
the three sections of the envelopes. Additionally, the line above the soft buttons lets you make
use of the Impact feature, which adds an amplitude overshoot to the Þrst 20 milliseconds of a
noteÕs attack. ItÕs important to keep in mind that if you set up an envelope control source, it
affects Envelopes 2 and 3, as well as the amplitude envelope (Natural or User). Furthermore, the
values for the various parameters are cumulative. With the exception of Impact, though,
ENVCTL does not affect the attack sections of natural envelopes.
The parameters and values in the following list apply to each of the three envelope sectionsÑ
attack, decay, and release. WeÕll describe them only once, since their functions are largely the
same for each envelope section. The only difference is with velocity tracking, which is
hard-wired to control only the attack sections of the envelopes (you can assign attack velocity as
the value for the Source parameter in each of the sections, however).
The values of each of these parameters multiply the rates of the envelope sections they control.
Values greater than 1.000x make the envelope sections run faster (they increase the rate), while
values less than 1.000x make the envelope sections run slower. Say for example that on the
current layerÕs AMPENV page you had set the Decay sectionÕs time at 2.00 seconds, and its level
at 0%. This sets the layerÕs amplitude to fade to silence two seconds after the completion of the
last attack segment. The decay time is two seconds; the decay rate is 50% per second. Now if you
select the ENVCTL page and set the Decay Adjust parameter to a value of 2.000x, youÕve
increased the decay rate by a factor of two. The rate increases to 100% per second, and the decay
time is now one second instead of two.
