<h2>Performance</h2>
<p><span class="emphasis"><em>kchan</em></span> - The MIDI channel to trasnmit the note on. Note that MIDI channels are numbered starting from 0.</p>
<p><span class="emphasis"><em>knote</em></span> - The MIDI note number to send.</p>
<p><span class="emphasis"><em>kveloc</em></span> - The MIDI note's velocity.</p>
<p><span class="emphasis"><em>kdur</em></span> - The MIDI note's duration in seconds.</p>
<p>Note: Be sure the instrument containing vstnote is not finished
before the duration of the note, otherwise you'll have a 'hung'
note.</p>
