This was one of the early generation instruments, brought down from MIlls by Pauline Oliveros. There were four sequencers (two 16-step and two 8-step), each with its own pulse generator. It was possible to run any combination of these either asynchronously or triggered by the same clock. Therefore there could be prime-number beat-locked combinations of primes such as 2, 3, 5, 7 or 3, 5, 7, 11 or 5, 7, 11, 13 or some combination of those phrase lengths. If you were clever, you could get even longer phrase lengths. -- ______________________________________________________________ Richard Zvonar, PhD (818) 788-2202 http://www.zvonar.com http://salamandersongs.com http://ill-wind.com
