Connector Protocol V2:

Latency compensation: Connector can now evaluate, compensate and report the latency of the connection.
Transport synchronization: Connector can now send MIDI Timecode (MTC) and MIDI Clock compatible signals to synchronize applications together.
Manage synchronization with clock anticipation: the clock signal can compensate the connection latency to synchronize apps with no delay.
