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 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!" .

I'm currently very impressed with the level of understanding and of interest in listening that I experience wherever I go. That motivates me to dig deeper into what I've been doing all of this time, to find new ways and also to get over the thought that it's not happening.

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.

[Improvisation ] is been with me all my life. We all do it.

I felt a challenge to compose music. That's where my challenge was, for the most part.

Something that I did, and I developed out of that sonic meditations, which were pieces that I composed in the '70s that now are very well-known and used in many classrooms all over the world, but at the time were outrageous.
