This is an expressive instrument created by musicians for musicians.

 

 DIRECTED BY DON BUCHLA, the 400 development team includes composers and performers as well as experts in man-machine interface, electronic design, computer science, and psycho-acoustics. Mr. Buchla's professional background includes space biophysics research, multimedia composition, the performance of avant garde and traditional music and the design of both acoustic and electronic instruments. As a Guggenheim fellow, he recently completed research in interactive performance-oriented computer music languages, and as an NEA fellow, he is currently designing instrumentation and music for a hundred piece electronic orchestra.

"Don is easily among the most advanced and imaginative of the instrument builders of the 20th Century."

"I have to admire what Don Buchla has done. He hasn't allowed himself to limit the complexity of his instruments to meet the demands of the so called 'market place' ...As a result, I think of all the systems that are available, his can be organized in arbitrarily complex ways most easily."
