53<h2>Description</h2>
54
55<p>This function registers callbacks for specified MIDI controller events. The user may insert MIDI controller events in the MIDI file to signal events at runtime.</p>
56
57<p><em><strong>NB:</strong></em> Callbacks are registered for specific MIDI controller events for all sequencer tracks. The <CODE>SEQCALLBACK</CODE> function will inform the user of track events by passing the pointer to <CODE>SEQTRACK</CODE> for the track, and register the controller event.</p>
