"Double" Looper Functions?

["Brian Thomson, London UK" <bnt@email.com> (by way of Kim Flint)]

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. It would be great if it were possible to multiply the loop
in real-time, without glitching of any sort.

So, if the original loop was 4 seconds, hitting the "double" footswitch
would immediately, seamlessly, duplicate the loop, to 8 seconds. 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%. So, a note that sounded at 1 second into a
4 second loop, would be duplicated at the 3 second point.

Comments, anyone? Or have I just restated the obvious?
