--[[
This function is called for each incoming MIDI event.
This is where the codec interprets the message and translates it into a Remote message.
The translated message is then passed back to Remote with a call to remote.handle_input().
If the event was translated and handled this function should return true, to indicate that the event was used.
If the function returns false, Remote will try to find a match using the automatic input registry defined with remote.define_auto_inputs().
