	<h3>Functions</h3>
	<p class=func><span class=keyword>noteOn</span>();</p>
	<p class=desc>Begin the delay to attack, or the attack phase is
		delay is zero.
	</p>
	<p class=func><span class=keyword>noteOff</span>();</p>
	<p class=desc>Begin the release phase.
	</p>
	<p class=func><span class=keyword>delay</span>(milliseconds);</p>
	<p class=desc>Set the delay from noteOn to the attach phase.  The
		default is zero, for no delay.
	</p>
	<p class=func><span class=keyword>attack</span>(milliseconds);</p>
	<p class=desc>Set the attack time.  The default is 1.5 milliseconds.
	</p>
	<p class=func><span class=keyword>hold</span>(milliseconds);</p>
	<p class=desc>Set the hold time.  The default is 0.5 milliseconds.
	</p>
	<p class=func><span class=keyword>decay</span>(milliseconds);</p>
	<p class=desc>Set the decay time.  The default is 15 milliseconds.
	</p>
	<p class=func><span class=keyword>sustain</span>(level);</p>
	<p class=desc>Set the sustain level.  The range is 0 to 1.0.  The
		gain will be maintained at this level after the decay phase,
		until noteOff() is called.
	</p>
	<p class=func><span class=keyword>release</span>(milliseconds);</p>
	<p class=desc>Set the release time.  The default is 30 millisecond.
	</p>

	<p class=exam>File &gt; Examples &gt; Audio &gt; MemoryAndCpuUsage
	</p>
	<h3>Notes</h3>
	<p>To achieve the more common ADSR shape, simply
        set delay and hold to zero.</p>
	<p>The recommended range for each of the 5 timing inputs is 0 to 50
		milliseconds.  Up to 200 ms can be used, with somewhat reduced
		accuracy</p>
