loop-based installations

["Rainer Thelonius Balthasar Straschill" <rs@moinlabs.de>]

I'm currently doing first attempts in doing a loop-based sound 
installation:
What I'm trying to do is a setup with several microphones, speakers and
loopers.
The microphones feed the loopers (which are set to feedback=0 in a first
try), the loopers feed the speakers.

Did anyone of you gather experiences with this kind of thing? Especially
with regard to controlling signal levels and fighting feedback in a
computer-based installation?
