Some chorusing No there isn't. The SAD1024 is obsolete, out-of-date, off the books. It has been replaced by better chips. Ask your local dealer.

That's all she does, including the films, slides, movement, dance, rituals, stories, phoning someone one the same stage, making fun of people with glasses in the audience, walking into the audience, animated films, films of films at concerts, etc. re: laurie anderson >All the ``cute'' effects and so on *do* have some point. For instance, the >words on the tape violin are part of a story, but taken by themselves make >no sense. (I think the words on the tape are ``Have you ever taken a test >in a Dairy Queen on another planet?'') I still think she integrated the tape-bow violin with what's-his-name's electronic violin. The tape head seems to be chin side of the bridge. it's: "I dreamed I had to take a test in a Dairy Queen on another planet." Why? because she read all this SoHo underground poetry in little magazines, and and they and they were and they were really and they were really into repeating and accumulating words, as I do in my slowasleep, saturday night 29 mar 86 mobius boston by fort point channel. using the tape-bow violin let's her do that with tape. First she plays just the beginning of the tape "I" then a little more "I dreamed" then a little more "I dreamed I" "I dremaed I had to take a test" then backwards "tset a ekat ot dah I deamerd I" "I dreamed I had to take a test at a Dairy Queen" the first punch-line repeat that a few times "I dreamed I had to take a test at a Dairy Queen" "I dreamed I had to take a test at a Dairy Queen" "on another planet" the second punch-line. -- >John Labovitz ..!{rlgvax,seismo}!bdmrrr!potomac!jsl > There are two ways of changing the delay in a digital delay: > change the number of samples between recording and playing or > change the rate at which samples are being recorded and played > (just like a "shift register" type of analog delay).

The DOD Digitech delays for rack mount at the low cost end have one clock, one counter, and the address the counter points to is first read then written to. Then the address is incremented. There are range buttons marked "flange, chorus, double, delay" that select the fraction (2**n) of RAM used, and a vernier marked "delay" that changes the clock rate. TOm DEC Marlboro MA
