This would be so cool to play with a Launchpad! Alas, I have a Mk2, not a Mk3...
Oh no! Out of interest I went to look up the programmer guide for the MK2, and while many of the commands are similar the core ones are a little different, as are the button values, so it's not an easy swap. It is fully playable with mouse and keyboard if you're still interested and haven't tried it already though!
