  27 <p class="p3">MIDIClient is a static class that starts up the MIDI service:</p>
  28 <p class="p3">It initializes with a number of virtual inports and outports.</p>
  29 <p class="p3">The default is 1. and usually not more a needed.</p>
  30 <p class="p3">The information about the hardware is stored in MIDIClient.sources and MIDIClient.destinations as MIDIEndpoints.</p>
  31 <p class="p2"><br></p>
  32 <p class="p3">MIDIIn represents a connection between a inport and a source of the MIDIClient.</p>
  33 <p class="p3">There are three possibilities to connect them:</p>
