title: How can I use MIDISend to play a midi file on a connected synthesizer?
body: <p>I am wondering if someone has any insights on how to send a midi file to a connected synthesizer? I played with MIDISend and MIDIPacketList but all the notes end up playing at the same time. I then tried to use dispatch_after and call MIDISend with individual notes this way but I am getting some very strange behaviour.</p>
