The San Francisco Tape Music Centre was a kind of collective non-profit that my friends and I got started so that we could pool our equipment and make tape music.

One day I decided I would like to put a record into my system. So I picked up a record that was lying on the table, and put it on. I didn't bother to look at what it was because I didn't care, and it turned out to be Madame Butterfly. So I processed the aria from Madame Butterfly in my system and I played with it.

Radio broadcasting was only 25 years old when I was born in 1932.

That change happened about 1991. It was not possible to transfer the Expanded Instrument System to the computer until then, when 16-bit recording became available.

I'm very interested in vertical space.I want the players to listen to their sound in such a way that they hear the complete sound they make before they make another one. So that means that they hear the tail of the sound. Because of the reverberation, there's always more to the sound than just the sound.

Those people who don't have any voluntary control, or hands, can work with the physical movement that they can do - whatever voluntary movement they have, even the slightest .

I feel that students always learn more from each other than they do from their professor. They learn by doing and not by trying to soak up information from one person.
