"Great little app. I am an e-musician and if you really get into that scene, you see that it is all dominated by the 'tyranny of the groove'. So much crap in 4/4 time, loop-a-dupe... It's just really refreshing to hear the intelligent chaos this software produces. I feel my sonic pallette cleansed. And to be able to have a hand in controlling the unpredictable results! Yeah, I'll throw out a web of unpenetrable, post-GarageBand soniphrabletonica!" (soundman)
Amazing Maze explored by students at CMMAS, Morelia (Mexico)
Masterclass on Algorithmic Composition given by Karlheinz Essl, 25 Aug 2011
Amazing Maze is a work-in-progress that started in 1993 when I was working at IRCAM (Paris). In this realtime composition I attempted to realize ideas that have been haunting me for many years, and which I first accomplished in Lexikon-Sonate (1992-2007) for computer-controlled piano. Both pieces envisage a new type of music
- which composes itself at the moment of its sounding
- which is not merely a reproduction of a pre-fabricated notation
- which is capable of reacting on exterior influences
- which exhibits infinite temporal expansion
- which never repeats itself.
Amazing Maze is represented by a computer program which generates music by manipulating sampled instrumental sounds according to certain compositional strategies that are carried out in different structure generators. Each generator synthesizes its own characteristic sound world.
The compositional algorithms are currently programmed in MaxMSP by taking advantage of my Real Time Composition Library (RTC-lib). This collection of software modules offers the possibility to experiment with a number of compositional techniques, such as serial procedures, permutations and controlled randomness.

vs. 3.0 (2014)
The sound material used in Amazing Maze is based on instrumental interpretations of three different types of sounds: points, grids, and planes which have been worked out for different instruments exploring sound qualities beyond the normal playing. This was done in collaboration with the following musicians:
|bass clarinet:||Donna Wagner (Vienna)|
|flute:||Sylvie Lacroix (Vienna)|
|prepared piano:||Florian Müller, Karlheinz Essl (Vienna)|
|percussion||Elisabeth Flunger (Vienna)|
|vocals:||Trevor Wishart (UK), Karlheinz Essl (Vienna)|
|saxophone:||Jeremy Ruthrauff (Chicago)|
|accordeon:||Ute Völker (Wuppertal)|
|electric guitar:||Bruno Reininger (Vienna)|
Additional samples have been extracted from Karlheinz Essl's instrumental compositions met him pike trousers (1987) for large orchestra, et consumimur igni (1990) for three ensemble groups and à trois / seul (1998) for string trio. In total, the piece includes more than 300 tiny sound particles which are used as the sonic material for various algorithmic composition procedures.
NB: Please note that this freeware represents a composition by Karlheinz Essl that you might use for your private recreation. The included sounds are an integral part of the composition which cannot (and must not) be changed.
Here you can listen to an excerpt which was generated automatically by the Amazing Maze software. Thanks to Keith Bramich and Cadenza MIDI Diary for posting and hosting this soundfile.
Originally, this piece was conceived as a hermetic sound installation (implemented on IRCAM's Signal Processing Workstation ISPW and running on a NeXT machine) which generates music on-the-fly in a completely unforeseeable manner without repeating itself. In 1996, this version (called "Realtime Composer") was ported to the Apple Macintosh computer using Max as the programming language.
During an extensive E-mail contact with the Chicago-based composer R. Albert Falesch Amazing Maze transformed itself into a computer-based electronic instrument. In this form Mr. Falesch premiered the piece at the Chicago International NEMO'96 Festival on the computer together with the bass clarinetist Gene Coleman.
An E-mail based contact with the electronic cellist Jeffrey Krieger led to a new phase in the development of Amazing Maze. Thanks to his demands and suggestions the piece was modified into an improvisation environment for live performers, where the soloist also takes control over the behavior of the structure generators by the means of different control devices suchs as MIDI pedals and buttons:
Amazing Maze, an interactive computer environment by Karlheinz ESSL (Austria) is a computer program written in Max that allows the performer a great deal of interaction. The performer uses MIDI pedals and the computer keyboard to ‘steer’ the improvisation. But the fingerboard of the e-cello can also trigger events as well. Through the use of the pitch-to-MIDI converter the performer is able to trigger sound files within the computer or tell the computer to compose a motivic idea. The computer acts like a ‘virtual’ partner composing music according to a set of compositional algorithms. The instrument takes on a new feature of being an actual controller as well as a sound generator. The work is for the advanced e-cellist. (Jeffrey Krieger)
Due to the collaboration with the oboe player and composer Joseph Celli (New York), I customized a version for him and his Yamaha WX7 MIDI horn. Afterwards, a version of the piece was done for the British percussionist Paul Peterson (Les Mans) and his drumKAT percussion controller.
In 1998 I started to developed an extended solo computer version for my own performances which is called m@ze°2 (Modular Algorithmic Zound Environment). Here I use an Apple Macintosh Laptop with all its control facilities (keyboard, mouse) and attached MIDI controllers as an electronic instrument for live performances and improvisation. It also incorporates realtime sound synthesis and processing routines.
In 2000, the piece was again completely rewritten in MaxMSP for an interactive sound installation that was presented at the new museum of the Essl Collection (Klosterneuburg/Vienna) and at DEADTECH in Chicago.
Seven years later I rewrote the piece again and released it as freeware which runs on all newer Apple Macintosh machines, including those with Intel processors.

Amazing Maze 3.0 for Windows is compatible with Microsoft Windows-XP or later. It has been tested on Windows-XP and Windows-7. It is also expected to function properly on Windows Vista and Windows-8. Selection of audio output drivers is flexible: In the Max DSP window (Audio Status) window, select any default Windows audio driver, such as ad-directsound, ad-mme, or select ASIO if your soundcard uses that. Default drivers may impose greater latency than the typical ASIO driver, but that should be of no significance in a generative application such as AmazingMaze.

generative sound file shredder
REplay PLAYer is a computer program that de-constructs a given sound file and re-composes it by using realtime composition algorithms. It can be used as a tool to generate an infinite and every-changing sonic stream from a single sound file for artistic, compositional or mere recreational purposes. It can also be regarded as a computer based instrument for live performances, as an interactive sound installation or a generator for ambient music.

fLOW is an audio computer program running on Apple Macintosh machines. It generates an ever-changing and never repeating soundscape in real time that fills the space with flooding sounds that resemble - metaphorically - the timbres of water, fire, earth, and air. This ambient sound scape generator adjusts itself through various parameters and controllers that are represented in real time on your screen.
