+<p>This tracks an incoming signal and outputs the result.</p>
+<p>The rate controls tell the plugin how quickly to respond to a change in
+input. Low values will mean a slower response - a setting of 0 will hold the
+last value, and a very high value will track the input exactly.</p>
+<p>Attack rate is how quickly an upward change is tracked, and Decay for
+downward changes. There are two pairs of these - the one used depends on the
+level of the Gate.</p>
+<p>Example uses:</p>
+<ul>
+  <li>
+  <em>An envelope tracker</em>- use the &#8216;Gate Low&#8217; track rates with
+  the Gate held low, and run the output through a full-wave rectifier (an ABS()
+  operator) to get an estimate of the level of a signal.</li>
+  <li>
+  <em>Sample and Hold</em>- run a narrow pulse wave into the gate, set the
+  &#8216;Gate High&#8217; rates to maximum, and the &#8216;Gate Low&#8217;
+  rates set to 0.</li>
+  <li>
+  <em>Track and Hold</em>- run a variable pulse wave into the gate, set the
+  &#8216;Gate High&#8217; rates to 0, and the &#8216;Gate Low&#8217; rates set
+  high. Varying the pulsewidth will vary the time the input is tracked, and
+  when it is held.</li>
+</ul>
