This is exactly what the multiply function in the echoplex does. Great idea, but Matthias thought of it sometime around 1985! It was implemented first in something he hacked together out of a Lexicon PCM42, then was implemented in his Paradis LoopDelay in '92, then of course in the Echoplex '94. Check out his story on the echoplex page: http://www.annihilist.com/loop/tools/echoplex/OBechoplexhistory.html It also lets you add material while you multiply, so it is very quick to get something like a 1 bar loop repeated 4 times with a 4 bar melody loop over the top. Check it out, the function has many more aspects that allow for all kinds of creative use. kim At 09:40 PM 11/1/99 -0500, Brian Thomson, London UK wrote: >Hi there: I've been thinking about an idea I had, which would be useful if I were ever designing a looper (hardware or software). > >Imagine the following scenario: I have a short loop set up, filled with suitable sounds.

The effect would initially be inaudible, since I'd simply have the original loop playing twice, but I could then add more sounds, and duplicate again if necessary. It might even be possible to "triplicate", "octoclate" (?), etc. by sending different controller messages. > >An alternative version might involve duplicating the audio, but within the _same_ time, but offset by 50%.
