Hi steffanko
Basically what we have achieved is we have 'hi-jacked' the MIDI data Traktor sends out in order to get track names and artist names to appear on Denon (DN4500 compatible) decks so we can get this info on the displays of our own custom MIDI controllers. We use Arduino with MIDI capability to capture this information that is intended for the Denon, and display it on our own LCD screens :)
