affected by the combination of the values produced by KeyTrk and VelTrk. Also note that unlike
previous Kurzweil models, ENVCTL does affect 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 first 20 milliseconds of a note’s attack.
The 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. The only difference 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).
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
at 0% . 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, making it twice as fast. The rate increases to 100% per
second, and the decay time is now one second instead of two.
Note: Since 0 multiplied by any number equals 0, the envelope parameters on this page will have no effect
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.
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).
