Mobile devices offer an ideal combination of user friendly combination, computational power and sound production capabilities. This allows us not only reproduce the original UPIC in a far smaller scale, at a far smaller cost and thus far more accessible. This UPIC iteration also allows for more improvisation and a more frivolous use, since the original was regarded as an exotic composition tool de facto constrained to a small number of composers and institutions. Of course, a mobile device offers that much of screen space, thus making next to impossible the drawing of such a detailed composition as ''Mycènes Alpha (1978)'' | Mobile devices offer an ideal combination of user friendly combination, computational power and sound production capabilities.

A user can choose between three different modulations (''sine'', ''triangle'', ''square'' waveforms) by clicking on one of the three differently colored buttons. This way, a '''red''' line stands for a ''sine'' waveform, a '''green''' line for a ''triangle'' and a '''blue''' line stands for a ''square'' wave. An '''undo''' button allows to step back and delete the last line(s). With the '''pinch-out''' gesture, all interface elements (buttons & slider) vanish, so that the whole canvas is available for drawing (pinch-in brings everything back) To clear the canvas, the user has to '''double tap''' the canvas. The user can '''play/stop''' the composition, control '''playback speed''' by moving the slider and also play in '''loop'''. | |||
When playing, a needle indicates the position on the drawing/partiture. | |||
===Mechanics=== | |||
The app consists of 4 Classes: | |||
The '''main''' class where everything starts (not much interesting happens here). | |||
The '''UpicAppDelegate''' is the application delegate (you guessed that!) | |||
The '''UpicViewController''' controls the only View of the UPIC app. When a user draws a line, the ''UpicViewController'' creates an instance of '''SoundVector''' which is charged with storing the point2d-path the line consists of, and also transforming this point2d-path into sound. Two-dimensional points are stored in an [http://cocoawithlove.com/2008/12/ordereddictionary-subclassing-cocoa.html '''OrderedDictionary''']. SoundVector instances themselves are also stored in an ''OrderedDictionary''. Of course, all user interaction (painting, undoing, playing, controlling speed and loop) is handled by the ''UpicViewController''. | |||
==App Store== | |||
We expect to have finished polishing the app by the end of September 2011 and by then have it submitted to the AppStore. (The app is already fully functional) | |||
