Envelopes 2 And 3; The Envelope Control (Envctl) Page - Kurzweil K2000 - MUSICIANS GUIDE Musician's Manual

Envelopes 2 and 3

The K2vx offers two envelopes in addition to the amplitude envelope. Like the amplitude
envelope, Envelopes 2 and 3 can be assigned like any other control source. The only difference
between these two envelopes and the amplitude envelope is that Envelopes 2 and 3 can be
bipolar. This means that you can set negative values for them. (Obviously, you canÕt have an
amplitude less than zero, so the amplitude envelope 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.

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.

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.
