  36 <p class="p3">This document explains technical details of the MIDI hardware interface class, MIDIIn.</p>
  37 <p class="p4"><br></p>
  38 <p class="p3">MIDIIn is a simple and direct interface.<span class="Apple-converted-space">  </span>When MIDI events come into Super Collider, MIDIIn evaluates simple handler functions.</p>
  39 <p class="p4"><br></p>
  40 <p class="p3">For general programming, <b>users should not use the MIDIIn class directly</b>.<span class="Apple-converted-space">  </span>See the <a href="MIDIResponder.html"><span class="s1">MIDIResponder</span></a> classes for higher level event matching and more flexible handling of event handlers.</p>
  41 <p class="p4"><br></p>
  42 <p class="p3">Certain MIDI messages are supported only through MIDIIn. These are: polytouch, program, sysex, sysrt, smpte.</p>

  47 <p class="p4"><br></p>
  48 <p class="p3"><b>MIDIIn </b>links MIDI input received from the operating system to a set of user defined functions.</p>
