<p>
<span class="emphasis"><em>vincr</em></span> (variable increment) and <a class="link" href="clear.html" title="clear"><em class="citetitle">clear</em></a> are intended to be used together. <span class="emphasis"><em>vincr</em></span> stores the result of the sum of two audio variables into the first variable itself (which is intended to be used as an accumulator in polyphony). The accumulator is typically a global variable that is used to combine signals from several sources (different instruments or instrument instances) for further processing (for example, via a global effect that reads the accumulator) or for outputting the combined signal by some means other than one of the <span class="emphasis"><em>out</em></span> opcodes (eg. via the <a class="link" href="fout.html" title="fout"><em class="citetitle">fout</em></a> opcode). After the accumulator is used, the accumulator variable should be set to zero by means of the <span class="emphasis"><em>clear</em></span> opcode (or it will explode).
