The power of randomness combined with your touch creates an endless melody for your enjoyment. Jazz guitar virtuoso Paul Musso combined his musical knowledge with the programming and artwork of Bryan Leister to create this music-making application. Musso provided guitar recordings of chords typically used to create a melody - F#, D#, C and G. Your touch (supports up to 4 simultaneous touches) creates collisions that will trigger one of these chords. Every 3 seconds, the key is randomly changed to either A Minor, C, F or G. The result is an amazing, soothing and endless melodic tune that you can play for hours without the tune ever repeating itself. The visuals provide an ambient backdrop to help you play. The capsules represent your touch, each moving dot is a physics-enabled ball that contains one note. Hit a ball, and the note plays. If the ball hits the edges of the screen, the collision also triggers the note. An experiment in music theory that was produced for an exhibition in Denver that also used motion tracking. Now available as a touch screen application.

Are you tired of people bombarding you with song requests while you’re on aux? Are you tired of the person on aux not appreciating your top notch song recommendations? Jup is an iOS app made to facilitate group participation within a music queue, allowing individuals to choose songs that will be directly added to the host’s active queue. The ‘host’ is able to choose to have their queue playing either on Apple Music or Spotify. The app will then function to use the music player of the selected service. Either service requires the host to have an active subscription with either service. The host can open up the queue via Bluetooth for nearby ‘participants’ to join. Participants, upon joining a queue, may add songs by searching either the Apple Music or Spotify music catalog regardless of having a subscription or account. Participants, upon signing in to a given music service, will also be able to access their personal playlists with that service to add songs from. Participants get a say in what songs are played next, via the ‘voting’ feature. Songs with the most votes get pushed to the top of the queue. The host can intervene by placing the queue in ‘host control’, where voting is disabled and the host can rearrange the queue if needed.
