Re: "Double" Looper Functions?

[Kim Flint <kflint@ati.com> (by way of Kim Flint)]

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.

necessary. It might even be possible to "triplicate", "octoclate" (?), etc.
by sending different controller messages.
