The Envelope Control (ENVCTL) Page

the Attack and Release sections on this page apply to the attack and release sections on the
AMPENV page. It’s important to keep in mind that the values for the various parameters
are cumulative, meaning that if for example you set attack to be controlled by Keytrk and
VelTrk, the resulting change on Attack would be aected by the combination of the values
produced by KeyTrk and VelTrk. Also note that unlike previous Kurzweil models, ENVCTL
does aect the attack sections of natural envelopes. Additionally, the bottom line of this page
lets you make use of the Impact feature, which lets you boost or cut the amplitude of the rst
20 milliseconds of a note’s attack.
e parameters and values in the following parameters list (see below) 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. e only dierence is with velocity
tracking, which is only available as a parameter to control attack sections of the amplitude
envelope (however, you can assign attack velocity as the value for the Source parameter in
each of the sections).
e 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 at 0%. is sets the layer’s amplitude to fade to silence two seconds
after the completion of the last attack segment. e 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, making it twice as
fast. e rate increases to 100% per second, and the decay time is now one second instead of
two.
Parameter Group (Available for
each of Att, Dec, Rel, Imp)
Range of Values
Adjust 0.018 to 50.000x (-24.0 to 24.0 dB for Imp)
Key Tracking 0.018 to 50.000x (-2.00 to 2.00 dB for Imp)
Velocity Tracking 0.018 to 50.000x (Not available for Dec or Rel; -24.0 to 24.0 dB for Imp)
Source Control Source List
Depth 0.018 to 50.000x (-24.0 to 24.0 dB for Imp)
Note: Since 0 multiplied by any number equals 0, the envelope parameters on
this page will have no eect on any AMPENV sections set to 0 seconds. A way
around this is to change any AMPENV sections set to 0 to 0.02 seconds.
