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.

Before that, an 8-bit recording was pixelated; it was really bad. It didn't serve what I was doing, which was recording live sound and delaying it and feeding it back. This is essentially what the EIS system is: a bunch of delays.

I think that this performance with the Thingamajigs is going to be an exploration of the acoustic space and particularly the vertical space, which we don't think about so much.

When we had the San Francisco Tape Music Center, we had a couple of Ampex tape machines there, and I could string tape from one machine, past the heads, and over to the next machine to the supply-reel amp, and have another delay there.

I have a commission to do a piece in a place in California, Oliver Ranch, which has an eight-storey structure called The Tower designed by the visual artist Ann Hamilton.

I think the worst thing is stereotyping.

I can't really deal with buttons. And that's what I keep saying, "Okay, I can't push buttons, because that means I have to take my hands off the keyboard or the buttons or whatever. Don't you understand!" .
