The code has now been migrated to GitHub: https://github.com/petejefferson/denon_dn. Future updates will be made there.
It’s hoped that it will give the project new visibility and invite others to contribute.
It’s still very much in it’s infancy, but I’m now devoting more time to improve it and support other models, and plan on doing a MIDI interface so it can be used with Mixxx and other DJ software.
