Some interesting things I bookmarked on del.icio.us on March 31st, 2008:

• Deviant Synth - Alternate MIDI controllers - roundup of alternative commercial (and vaporware) MIDI controllers, covering a variety of approaches to key-layouts and interface.

The Continuum by Haken Audio, $3390 for half-size, $5290 for a full-size board.

• Gloggomobil: Programmable Music Machine - The wooden barrel is spun by means of a hand-crank on the side. Small pegs are inserted into pre-drilled holes in the barrel to determine what note plays and when. The music plays on a small-scale metallophone or Glockenspiel (like a xylophone but with metal tuned bars rather than wood).
• Terje Isungset - Norwegian musician and percussionist who primarily plays intruments made from ice.
• Zizzle Zoundz - Zoundz creates a fusion of self- composed music with an accompanying light show. Create your own riffs by placing one of Zoundz's pawns on an interactive “hot spot” on the sound board.
