A lot of early works using tape delay systems also used multiple amps and speakers. Pauline Oliveros on others at the San Francisco Tape Music Center in the 1960s did a lot of pieces that way. It made particular sense for those low-buged guerrila electronic days when it was probably more common to have tape decks with built-in speakers than professional PA systems with decent mixers. We used to do performances in the mid-70s with surround quad and dual-deck 4-track tape delays. Playback from the first deck would go into the front speakers and playback from the second deck would go to the rears, so we had both short and long delays. I did a lot of performances in the '80s using surround quad and multiple digital effects. The most fun was the Diamanda Galas gigs, where she used four microphones, each routed to a different speaker and to a different effect, and I would play freely with the routing of the effects outputs. I'd even route one effect to another, sometimes building up complex feedback networks on the fly. I did one theater piece with a multichannel system loaned by Yamaha. I had three DMP7 automated mixers, a TC2290, and an H3000, with multiple microphones hanging throughout the space (a huge warehouse that was part of the Santa Monica Museum) and (as I recall) an 8 channel speaker system. The mics picked up the actors voices and I'd loop and otherwise mangle them and circulate the results throughout the space. I did some similar things in San Francisco on a couple of big productions with a group called New Music Theatre. It was a similar setup (also with Yamaha support - thanks, Joel!) and also involved actors and singers. I haven't done much of this recently, but I've just acquired eight small speakers to do surround in my studio and this will probably lead to more live multichannel work. An advantage to using multichannel sound systems with looping is that different sound layers can be articulated spatially,thus avoiding muddy textures. If you set up a system which keeps the dry signal and processed or looped signals unmixed you can place each "voice" where you want it. This can be done with relatively modest equipment, since having more speakers allows you to keep the individual levels down. You can get by with smaller (and cheaper) individual components. -- ______________________________________________________________ Richard Zvonar, PhD (818) 788-2202 http://www.zvonar.com http://RZCybernetics.com http://www.cybmotion.com/aliaszone http://www.live365.com/cgi-bin/directory.cgi?autostart=rz
