<para>
<emphasis>midiout</emphasis> has no output arguments, because it sends a message to the MIDI OUT port implicitly. It works at k-rate. It sends a MIDI message only when <emphasis>kstatus</emphasis> is non-zero.
</para>

<para>
<emphasis>Warning:</emphasis> Normally <emphasis>kstatus</emphasis> should be set to 0. Only when the user intends to send a MIDI message, can it be set to the corresponding message type number.
