Hey. I need something like in this video: [url removed, login to view] (Here with Pure Data) Reactivision flucidal markers placed on a grand notion, mapped into corresponding sounds: x position - time, y - note/sound. May use ready-made samples or generated sounds. Needed option to switch between instruments (3 or 4). Play, stop button and loop playback are also necessary. String of text naming the note should be displayed, as well as playback marker vertical line.
