Norman Fairbanks released a new album "7 Days Microsleep", made with Yamaha's Tenori-on. The album can be downloaded from http://www.normanfairbanks.com/ (cf. http://www.yamaha-europe.com/yamaha_europe/uk/service/070_news_events/20071113_tenori_on_MusicLive/index.html) It seems Tenori-on is more than just a nice toy (my first impression).
