Ed Okerson writes, "at a DPRG club meeting a few months ago, some of the members were discussing building robotic musical instruments. Well, here is a very interesting application for a mechanically actuated piano." Ed's talking about Austrian composer Peter Ablinger's mechanically actuated piano which speaks by breaking human speech down into "pixels", each of which is a piano note. The voice processing and piano control was done using custom software developed by the Ablinger and run on a GNU/Linux machine. A translation of the German narration describing the process can be found in the "more info" section of the YouTube page.
