<p>Generates an ADSR (Attack, Decay, Sustain and Release)
envelope.</p> 

<p>Does the same thing as the other ADSR (1658) above, except the
Trigger Threshold is fixed at zero, and the additional Trigger
input allows retriggering whilst the gate is still high.</p> 

<p>The reasoning behind this design is to remove the need for a keyboard player
to release a key before pressing another when using with a monosynth.  <a
href="http://www.sospubs.co.uk/sos/nov99/articles/synthsecrets.htm">The
&lsquo;Synth Secrets&rsquo; article in the November 1999 issue of &lsquo;Sound
on Sound&rsquo;</a> explains this in detail.</p>

<p>The output is a signal between 0.0 (rest) and 1.0 (peak) and the
transitions are linear.</p>
