I'm not sure this message was sent correctly...I'll try it again. Sorry if its a repeat.... > >To start out a track, tap out a few beats on a footswitch.

"Discipline"). I have been doing something like this using multiple echolplexes, connected via the brother sync. I use one echoplex to create a "fundamental unit" loop. Then, I create loops on additional echoplexes, which are a multiple of this fundamental unit. Finally, I can go back to the original unit and mulitply its length too. Using four echoplexes, for example, I can have them repeating every 4, 5, 6, and 7 beats, respectively. This makes for some great entertwining melodies, which don't sound repetitious -- they sound like they are forever changing. Obviously, having multiple echoplexes can be costly...Currently my brother and I each have 2 units, so between us, we use 4 units. This also gives us the capability of separating them in space -- we are currently using a quadrophonic setup, with each looper given its own channel, adding a "spatial dimension" to the music. Another trick I like, is to run a loop through an effect, like a slap back delay, and sending this into another looper (and another channel). This makes for some "mind-tweaking" sounds. I am interested to know if anyone is using Opcode MAX to create custom interfaces with the echoplex. If This is something that I would like to undertake, but I would like to know if anyone as already doing this. If not, please send suggestions for interface capabilities. My idea is to use an ART X-15 footpedal to control multiple echoplexes. I'm still in the brainstorming mode, so suggestions are welcome! - Chris P.S. In a previous message, I had referred to the Setve Reich album as "Music for 16 Musicians" -- Sorry for leaving two musicans out....the correct title is "Music for 18 musicians". --------------------------------------- Chris Chovit cho@gomez.jpl.nasa.gov ---------------------------------------
