<span class="emphasis"><em>ichn</em></span> -- MIDI channel number (1-16)

<p>

<h2>Performance</h2>
<p>
<span class="emphasis"><em>noteon</em></span> (i-rate note on) and <span class="emphasis"><em>noteoff</em></span> (i-rate note off) are the simplest MIDI OUT opcodes. <span class="emphasis"><em>noteon</em></span> sends a MIDI noteon message to MIDI OUT port, and <span class="emphasis"><em>noteoff</em></span> sends a noteoff message. A <span class="emphasis"><em>noteon</em></span> opcode must always be followed by an <span class="emphasis"><em>noteoff</em></span> with the same channel and number inside the same instrument, otherwise the note will play endlessly.
</p>
<p>
These <span class="emphasis"><em>noteon</em></span> and <span class="emphasis"><em>noteoff</em></span> opcodes are useful only when introducing a <a class="link" href="timout.html" title="timout"><em class="citetitle">timout</em></a> statement to play a non-zero duration MIDI note. For most purposes, it is better to use <a class="link" href="noteondur.html" title="noteondur"><em class="citetitle">noteondur</em></a> and <a class="link" href="noteondur2.html" title="noteondur2"><em class="citetitle">noteondur2</em></a>.
