RE: surround looping revisited

["Hartung, Kris" <kris.hartung@hp.com>]

Got it. Thanks. Your application is interesting. I think I could figure it 
out now. In fact, in EnergyXT, I can assign any output of a VST to any of 
my 5 soundcard outputs (back L/R, front L/R, and center), and then I could 
run those soundcard outputs to separate powered PA speakers...or my mixer, 
using my main stereo out and sub outs.  Damn, I either have to buy a new 
laptop to run Mobius to loop all five channels independentaly, or buy 
three more EDPs...eithe option costs about the same....or I just loop my 
front L/R channels.  I have to stop thinking about this...very 
dangerous...I could fall into what my wife calls one of my vortexes and 
disappear in the basement for weeks. Not good, man.  Don't tell me anymore 
Rainer. This is grounds for divorce. ;)

Thanks four your feedback, Kris!

First, let me mention that this setup is more of an interactive 
installation rather than "normal" music. What I currently do is let it 
simply run and pick up street noises coming through the windows, incoming 
phone calls, toilet flush, espresso machine... and see what happens.

Now coming back to your questions, and I'll answer the last one first.
Check out the AcousModules web site acousmodules.free.fr (note that the 
English version of the page is currently not really functional - hope you 
speak some french ;-) Use the SpatDelays effect (its basically eight 
delays in one unit), send your (monophonic) source singnal to inputs one 
to four, turn on delays one to four with different delay times and send 
the output of delays one to four to your four speakers.

My current setup in AudioMulch looks like this (a setup you can replace in 
any of the modular audio thingies like Bidule or EnergyXT or even Nuendo 
I'm sure):

Inputs 1-4 (from Microphones)
V
one Buzz Compressor per channel with huge threshold, long release and 
strong limiting and lots of makeup gain V
4x4 Matrix
V
two EllotronixXL in stereo mode with decay centered (these act only as 
long delay lines)

The four independent delay outputs are used as inputs for several effects 
(some of them with surround outputs or inputs and outputs), several of 
them from the AcousModules website. The output of these is fed into four 
4-to-1 mixers which in turn feed the four independent outputs.


The speakers are set up in a kinda-quadrophonic fashion in my bedroom, the 
microphones are placed differently: one (AT4050 in figure-eight) sits next 
to the computer at the back end of the room, one (Rode NT-1A) is pointed 
at the window and picks up street noise as well as reflections from the 
window. A SP C4 pair (cardioid) is set up in the hallway, one mike 
pointing towards the living room.


Currently, I'm trying to fight the buildup of drones (hence my question 
about feedback destroyer plugins). These do form a kind of strange 
attractor for the system - meaning that independent of the input, after a 
finite time the system lands in "boooooooooooooooooooooohhhhh" mode :-(

Pretty cool, Rainer. It would be fun to setup a surround sound, live
system one day. I would probably buy two wireless speakers and put them
in the back of the room. I too have the creative labs surround
capability on my soundcard. Can you explain what surround effect you are
using? Are you taking advantage of the other set of stereo images and
running different signals/effects to them, or just running a dual stereo
system?  For instance, how would you setup a four way ping pong delay?

It's done!

Today, I set up my first surround looping setup, based on some of the
valuable opinions in this forum. About the setup:

Hardware:
        PC w/ ADAT Interface
        Behringer ADA8000 ADAT I/O (8 Mic/Line Ins, 8 Outs)
        Creative Labs pseudo-surround speaker setup :-)
        various (4) mikes (AT, SP, Beyer)

Software:
        AudioMulch
        Ellotronix looper (2)
        various AcousModules
        BuzzComp (4) (as kind of automatic gain control)

And the following two axioms:

        (1) No feedback internal to the electronic setup (i.e. only
feedback speaker -> microphone)
        (2) No signals fed from inputs to outputs which aren't run
through the delay lines


Short description: a 21st century interactive Alvin Lucier setup! I'm
still fine-tuning as well as expanding this approach, so again here come
more questions:

  * Does anyone know of a (if possible free or cheap) feedback destroyer
as a VST plugin? I'm thinking of basically a software version of the
Sabine/Shure/Behringer hardware units used for live sound applications.

  * Is there a nice interface to send ASIO connections via a network
connection (without using Steinberg Nuendo that is)?


Thanks for your input!
