 ### Added
 
+- The ability to provide most features with the Opus Quad, even though that hardware does not really support the Pro DJ Link protocol, by leveraging its ability to work with rekordbox lighting. Thanks to [@cprepos](https://github.com/cprepos) for doing most of this work!
 - The ability to proxy metadata from mounted archive files corresponding to USB media mounted in the Opus Quad, which cannot itself provide that information.

-to support lighting in a way that will allow us to offer good support in Beat Link
-once we reorganize the code to support working that way. There is
