So far, multichannel works for the Endangered Guitar have been performed on systems with 3 speakers, quad, 5.1 with displaced center speakers, hexaphonic systems, 7 channels (the eighth speaker was broken), octophonic / centered octophonic, 8-channel cube systems, 16 channels, 56 channels and a Wavefield Synthesis System.
MULTICHANNEL AUDIO / WORKS FOR SPACES
I am using multichannel sound systems on a regular basis since 2002, starting out with modified 5.1 surround sound systems in which I displaced the center speaker either to the center of the room or anywhere else as far the location allowed. However, since I had the opportunity to completely rewrite my multichannel routines in the Endangered Guitar Processing software at Lucas Artists Resiencies in Montalvo, Saratoga CA, I have been exploring other avenues. Originally working with traditional 5.1 systems that were widely available in the early 2000s, I created two independent voices drawn from the guitar and distributed (a) to a single speaker located elsewhere in the room, and (b) to a micropolyphonic/polyrhythmic pattern on the speakers surrounding the audience. I still use the two-voices approach even on systems with large numbers of speakers, except that the monophonic voice is now a moving sound source using vector based amplitude panning.
See a few examples from different approaches to multichannel sound using Max/MSP from over the years, but of course all you can hear are stereo downmixes.
Skeuomorph for FLUX Quartet and Realtime Immersive EnvironmentA sonic hybrid of FLUX’s acoustic sounds and their electroacoustic counterparts. The result of a 20-year investigation of electroacoustic live processing, it is conceived as a multichannel piece that can be presented on systems with up to 64 channels of audio.

Sonic Flotsam 2019
The sound sources are several contact mikes, primarily picking up the sounds from the battery-powered fans. Performances have been done on quad, hexaphonic and octophonic systems.
The Endangered Guitar on 56.2 channels at Stanford’s Center for Computer Research in Music and Acoustics!
CONFLICT OF INTEREST 2018
The spatialization on Harvestworks’ 8-channel cube system at Hunter’s is controlled by data from my own DNA analysis, and the electromyographic data from the MYO armband.
SCHWEINE IM WELTALL 2017
Processing Michael Vorfeld’s sounds that are generated by different light bulbs and actuating electric devices, on three-dimensional 8 channel cube system.
HfMT HAMBURG 2012:
WAVEFIELD SYNTHESIS SYSTEM
An Endangered Guitar performance. In regular multichannel systems sounds are still heard as coming from the direction of the speakers. Not so in Wavefield Synthesis Systems, here sounds are perceived as moving in space independently of the speakers, e.g. they can stop in front of your face, and travel through your head.
ARSON w/ DENMAN MARONEY 2013
Processing Denman Maroney’s “hyperpiano” on a quad system at the New York Electronic Arts / Rhythm in the Kitchen festival 2013.
ISSUE PROJECT ROOM 2006
Endangered Guitar at Issue Project Room, with 16 speakers hanging from the ceiling and one speaker in the back of the audience. John Jannone provides the live video processing.
BALANCE OF POWER 2005
The LEMUR GuitarBot (www.lemurbots.org) is a collection of four MIDI-controlled monochords built by Eric Singer. I set up a feedback loop between the Guitarbot and my software, in that the analysis of the Guitarbot sounds controlled the playing of the instrument. Presented as a 5.1 piece, it was shown on surround sound installations and presentations in the US, Germany and Bulgaria.
ENGINE 27 2002
Endangered Guitar performance at a residency at Engine 27, using 16 speakers of different sizes, at different locations in the room, and pointing in different directions. Also, the speakers were made of granite.
