LEXIKON-SONATE (1992-96) - an infinite and interactive realtime composition
environment - is now available as a standalone program.

It only requires an Apple Macintosh computer; an external MIDI-equipment is
not necessary, but can optionally be added. Thanks to QuickTime the musical
output is directly played throuh the loudspeaker of the computer.

System Requirements...¶
======================

     * Apple Macintosh (8 MB RAM min.), System 7.x
     * QuickTime 2.x
     * optional: MIDI-interface with a MIDI-instrument (piano sound)

About...¶
========

LEXIKON-SONATE is a interactive piece for MIDI-controlled player piano
which is composed and performed by computer software in real time. The
underlying program was written by Essl in MAX (Zicarelli and Puckette,
1990-1995 Opcode Systems Inc./ IRCAM), an interactive graphical programming
environment for multimedia, music, and MIDI, running on a Macintosh
computer. It draws from a large library of musical functions, compositional
techniques, and algorithmic strategies which Essl has developed over the
past few years: the "Real Time Composition Library" for MAX.

LEXIKON-SONATE consists of 24 music-generation modules which are related in
a very complex way as a musical HyperText. Each module generates a specific
characteristic musical output as a result of the compositional strategy
that has been applied. A module represents an abstract model of a specific
musical behaviour. It does not contain any pre-organized musical material,
but a formal description of it and the methods how it is being processed.
The idea of autopoiesis - material organizing itself due to certain
constraints - plays an important rule. By using a lot of different random
generators which are controlling each other (which - according to serial
thinking - form a scale between a completely deterministic and a completely
chaotic behaviour), new variants of the same model are generated. Variants
that may differ dramatically from each other, though they are always
perceptable as "inheritances" of the given structural model.
