The band uses this piece of equipment from time to time, such as in the hidden track at the end of Deserter’s Songs and on the track “A Kiss From An Old Flame” on SYOTOS. Grasshopper says, “A tettix wave is a musical machine that jonathan and I invented with U.S. patent pending…” Someone on the rev mailing list adds,”The Tettix wave accumulator takes up most of the room in Grasshoppers basement. A smaller version has been used on the road. I believe both Jonathan and he built it. I do not know whose idea it was originally.” I found another article, in which Grasshopper says, “The Tettrix was an idea I had to get a bunch of oscillators and, instead of controlling them through a synthesizer, I worked it so that you could plug anything into it and also store it on disc.
