I have been bedroom DJing, and wanting to expand what I can do with the hardware I already have.

Using `midiex` for Elixir I’ve written a fully fledged driver for Ableton Push, letting me use it as essentially a 4-deck version of Pioneer’s DDJ-XP2 sub controller with Rekordbox.

It implements basic statefulness so that the rotary encoders can be used, as well as a paging system so the 64 performance pads can be mapped to different functions. It also supports track browsing and loading, which is helpful if you want to use say DVS with an external mixer and don’t want to be hunched over a laptop dragging tracks around.

It’s also got some additional capabilities which I’ve not seen on other hardware like dedicated faders for stem separation levels.

It’s been a great exercise in combing two hobbies, learning about MIDI as well as being able to personalise my setup for my own use. I haven’t open sourced any of it just yet whilst I’m still tweaking things but I’d be interested in collaborating with anyone who also has one of these devices and has programmed it. I’m looking to use the display on it next, whose protocol Ableton have some (albeit scant) documentation for.
