MAKE pal and Roomba hacker Todbot show you how use the Roomba as a MIDI instrument, maybe we’ll have this running at the Roomba fights“The Roomba has a piezo beeper that can play tunes. You’ve heard it. And its motors make noise. Why not put them under MIDI control? So here is RoombaMidi: a Mac OS X application that creates a virtual MIDI instrument for use by any Mac OS X MIDI sequencer, like Ableton Live, Logic, and so on. If you don’t have a sequencer or just want to play with this quickly, grab the awesome and free app MidiKeys. It’s a little virtual MIDI keyboard.” [via] – Link.
