<p>STK <a class="el" href="classstk_1_1ADSR.html" title="STK ADSR envelope class.">ADSR</a> envelope class. </p>
<p>This class implements a traditional <a class="el" href="classstk_1_1ADSR.html" title="STK ADSR envelope class.">ADSR</a> (Attack, Decay, Sustain, Release) envelope. It responds to simple keyOn and keyOff messages, keeping track of its state. The <em>state</em> = <a class="el" href="classstk_1_1ADSR.html#ae1cdd1f2886d69a76fcd5b1e0e9154baa1ed3238253daecbdba14da71759392d8">ADSR::IDLE</a> before being triggered and after the envelope value reaches 0.0 in the <a class="el" href="classstk_1_1ADSR.html#ae1cdd1f2886d69a76fcd5b1e0e9154baa7efc189b0b53e581201fd64f357a1756">ADSR::RELEASE</a> state. All rate, target and level settings must be non-negative. All time settings are in seconds and must be positive.</p>
