Winfried Ritsch and IEM created the "Automatenklavier", using custom built electronics (PIC microcontrollers via multiple serial links from a computer: ALGOPIC. Voice analysis was done at IEM in Pd by Thomas Musil and Winfried Ritsch. The piano (there exist two versions) are also used in installations like Quadraturen and Quadraturen III7th Act: THE AUDIENCE is another piece which uses the pianos (via Pd), two movies (via Gem), audio playback and two ensembles playing the "Cityopera" Graz including video and audio examples. This was done by Ablinger with IEM Graz and Musil/Plessas/Ritsch/Zmölnig.

Good samples of the voice analysis can be found in Ablinger's pieces "Voices and Piano"
