Venue curated by Jorge Castro and supported by the Alzate Avendaño Foundation of Colombia.

Horace in San Mateo

A realtime algorithmic computer music and live electronics piece for "Fender Rhodes" (if possible) and pianoforte Sounds. The piece follows on the spirit of the augmented ninth dominant or plus eleventh chords seldom used by pianist Horace Silver on several of his compositions.


This is a sound installation as well as an eight-channel tape music composition. In this piece sounds travel a path inside a boxed environment obtained by Lissajous patterns applied to intensity panning on each source.


A sound art exhibit featuring Chuchoter as well as other works from various artists it the Museum of Modern Art of Bogota. This exhibit also featured talks on the subject matters of computer music and new ways of expression and performance.


A sound art exhibit featuring FtheF for visuals and modeled bowed strings and artificial performer. This is a multichannel composition and sound space intervention. Sound sources come from the physical model of the bowed string.


This is a new rendition of the original ``Freddie the Friedlander'' for physical model of the bowed string plus artificial performer. This version adds visuals and color in an attempt to image-by-synesthesia fabrication.


This is an algorithmic miniature piece for sound samples of saxophone. In its code the algorithm pursues J. C. Risset's rhythmic paradoxes, which in this case give the illusion of an ever lasting accelerandi o decrescendi. This piece is dedicated to music education advocate and winds performer Terry Mohn.

Art and Gesture Seminar

This is a course offered for students interested in symbols, semantics and grammars of gesture on various domains. Initially conceived for music performance students have also found applications on visual and space arts as well as dance and body art.

Not too recent but current:

Pages for workshop on Elements for Electroacoustic Composition

A tutorial for electroacustic composition or sound art production 'en español'. Used on several workshops at Universities and institutions throughout Latinamerica.

AVRLIB on Wiring and Arduino

Just in case if Wiring or Arduino frameworks are not enough. This pages are an introduction for using Pascal Stang´s AVRLIB and AVR-GCC on Wiring and Arduino boards.
