Creating an iterator on a MidiModel (Sequence) creates a read-lock on the same, which exists until the iterator is destroyed. This new designs renders the model/source to an RTMidiBuffer, then atomically swaps in a new RTMidiBuffer in an RT context. Not yet implemented in this temporary branch is handling required state-changing messages when the buffer is swapped.
