By default the IR Remote does not work with moOde, so I set about fixing this.
Full instructions on how I got my mappings working (in my case in conjunction with blissify for algorithmic playlisting / queuing) are available at the gist below.
For the most part this is mapping key events to MPC commands, but w/ blissify (which I really recommend!) you need to trigger shell commands, and of course need to set this up separately and analyse your library first.
