45<h2>Return Values</h2>
46<p>None.</p>

48<h2>Description</h2>
49<p>The <code>SEQRegisterControllerCallback</code> function registers callbacks for specified MIDI controller events. MIDI controller events can be inserted in the MIDI file to signal events at runtime.</p>
50
51<p><em><strong><B>Note:</B></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 with the pointer to <CODE>SEQTRACK</CODE> for the track, and register the controller event.</p>
