Sequitur Generator

software for realtime-processed live-electronics for Karlheinz Essl's Sequitur compositions


The live-electronics of Karlheinz Essl's Sequitur cycle is carried out by an individually programmed computer software - the so-called Sequitur-Generator written in Max/MSP. Each of the 14 Sequitur compositions uses an specific version of the Sequitur-Generator which generates a complex 8-part canon from the instrument's live input as an accompaniment. Unlike traditional canons, the individual canonic layers do not enter at regular intervals but in a sort of acceleration which results in an increasing structural density. Moreover, the single canonic layers are getting gradually distorted - as if the were decaying. And at last, the 8 parts do not always play together, but are constantly cross-faded by using random operations which results in every-changing and unforeseeable structural interactions where the canon can vary between 1 and 8 voices.
