The Envelope Control (ENVCTL) Page

6-45

This page is a table showing the ﬁve 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 ﬁrst 20 milliseconds of a
note’s attack. It’s 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

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 sections—

attack, decay, and release. We’ll 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 layer’s AMPENV page you had set the Decay section’s time at

2.00 seconds

, and its level

. This sets the layer’s 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

, you’ve

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.

Adjust

This is the familiar Coarse adjust found on many other pages. Use it here to change the rate of
one of the envelope sections without reprogramming the envelope itself. This parameter doesn’t
give you realtime control over the envelope. It is, however, a good way to adjust the natural
envelopes without switching to a User envelope and trying to approximate the Natural
envelope.

Key Tracking

This uses the MIDI note number of each key as the control input for the current layer’s
corresponding envelope section. When the value of this parameter is greater than

1.000x

, notes

above C 4 will make the envelope section run faster, while notes below C 4 will make it run
slower. When the value of this parameter is less than

1.000x

, notes above C 4 will make the

envelope section run slower, and notes below C 4 will make it run faster. This gives you realtime
envelope control right from your MIDI controller. You might use it, for example, to cause an
acoustic guitar sound to decay quicker at the high end (set the key tracking to a positive value).
