m@ze°2 is a computer-based electronic instrument which serves as a realtime environment for composition and improvisation as well. This project is another attempt to realize an old idea that has been haunting me for many years: the vision of a music

The software is written entirely in Max/MSP and takes advantage of my own Real Time Composition Library (RTC-lib). It is based on an ever-growing database of samples which are processed by so-called structure generators which are triggered and controlled by the computer keyboard, the mouse, several MIDI controllers and a webcam. An elaborated section of DSP routines (including reverb, harmonizer, transposer, pitch shifter, equalizer, LFO, ring modulator, and panning) enables the player to process the generated sound structures in the end.

NB: This software is not public domain. It is used by its author, the composer Karlheinz Essl, as an electronic instruments for his solo performances and improvisations with other musicians. However, several modules of m@ze°2 are available as free- resp. shareware: REplay PLAYer (a generative sound shredder), fLOW (an ambient sound generator), and Amazing Maze (an interactive realtime composition for sampled sound particles).
