Converts your beat-track labels from Audacity into a single MIDI file. You can then import it into LMMS to make your own Karaoke-style MP3's. At the moment I'm converting Lorde - Royals, so there's drum beat data from that song in there.
Run it, "See inside" then right-click the list, to import your own LabelTrack.txt You should be able to paste the output into any Hex Editor, so long as it retains the actual hex values, instead of trying to paste it as ASCII text. I found Jeex does OK for this task on Linux.
