"Gentlemen: I have a story that may be of interest to you. It is not widely known who invented the circuitry concept for the automatic sequential performance of musical pitches - now well known as a sequencer. I, however, do know who the inventor was - for it was I who first conceived and built the sequencer." This is the opening to an undated, unaddressed letter, found in Raymond Scott's personal papers (yes, the same fellow whose kooky soundtracks scored everything from Looney Tunes and Merrie Melodies to Ren & Stimpy, The Simpson, and Animaniacs). You can read the rest of Scott's letter, along with Bob Moog's recollections of visiting Raymond's electronics laboratory in the mid-1950s. Or you could jump ahead to the mid-1960s, when Jim Henson was in his late 20s to early 30s, and he was working on a variety of odd projects after a successful run with Sam and Friends, but before he it it big with Sesame Street. It was at this point that he teamed up with Scott on a few short, experimental films. [more inside]

Seaquence "...is an experimental musical petri-dish. Adopting a biological metaphor, Seaquence allows you to create and combine musical lifeforms into unique, dynamic compositions."
I received my nanoloop the other day and it is way cool. It's a techno tracker for gameboy. Another one you might find interesting is little sound dj.
