MEAPsoft: A Program For Automatically Segmenting and Rearranging Music

Press Here To Enter The Site: MeapSoft

MEAPsoft works by (a) segmenting original audio up into individual beats or events, (b) calculating some features for each segment, and (c) matching or rearranging segments from one or more pieces to create a new piece of music.

MEAPsoft comes with a wide and increasing range of feature extraction routines, and algorithms for matching and rearranging the segments (called “composers”). MEAPsoft is written in Java, and makes it pretty easy to write your own feature extractors and composers.

 

Lexikon-Sonate: Algorithmic Music Generator (OSX)

“Lexikon-Sonate is an interactive realtime composition environment for musical composition and live performances. It takes advantage of composition algorithms that has been developed by Karlheinz Essl since 1985. With this algorithmic music generator on can easily create fascinating and complex musical structures on the fly. Furthermore, Lexikon-Sonate is an infinite music installation that can run on a computer for years without repeating itself. Finally, Lexikon-Sonate can be used as an instrument for live performance of electronic music.”

 

MusicAlgorithms: Tools For Algorithmic Composition of Music

“Students of music composition can explore algorithmic composition, while others can create musical representations of models for the purpose of aural interpretation and analysis. Here, the algorithmic process is used in a creative context so that users can convert sequences of numbers into sounds.”

 

Stockhausen’s GAGAKU-CIRCUIT on Max 5-Avant-Garde Music Programming

“The GAGAKU-SCHALTUNG or Gagaku Circuit is a fundamental block in the construction of Stockhausen’s TELEMUSIK. It summarizes the idea of merging two distant worlds and obtaining as a result something which is more than the sum of the original parts. In fact amplitude modulation is exactly that: a nonlinear synthesis (i.e. it does not meet neither superposition nor proportionality criteria – G. Loy in Musimathics vol.2 – MIT Press 2007). Nevertheless, this circuit can be tuned to decode a modulated source if one knows the frequency of the oscillator used for the modulation. In the digital era, this can be accomplished with very little distortion in the output and it can be tested in this patch by tuning both oscillators (A and B) to the same frequency and only listening to the output of the modulation B. In structure 3 of the piece, there is a brief glissando at the end of the section, that shows the effect of going from the same frequency of 12000Hz in both oscillators to 50Hz below and back to 12000Hz again (try presets 1 and 2 for testing – see below).

We have prepared an introductory video that will guide you thru the steps needed to initialize and run the patch. You can also contact us thru the forums for help, questions, etc. Please find the video, and the links to the forum and download at the bottom of this page.”
