Collective comprovisation by BSBLOrk - Brasília Laptop Orchestra.
A composição Pulses é uma improvisação eletroacústica para orquestra de laptops baseada na exploração da relação paradoxal entre a simplicidade de timbres, a randomicidade de lances de dados e a construção da complexidade a partir dos resultados combinados. Começando como um mantra, uma simples onda senoidal que gera a nota Lá em 110 Hz, a peça vai sofrendo paulatinamente o efeito de sutis transformações resultantes dos lances de um dado de 10 faces para desenvolver, a cada realização, um processo sonoro imprevisível e irrepetível, ainda que holonômico e autosimilar, como as sequências fractais.

Pulses (2013)

This is a studio version for this experiment, which is intended to be improvised live by BSBLOrk - Brasília Laptop Orchestra, with a max patch that randomly selects fragments of Conrado Silva's Equus piece (1976) and plays them in a random speed and pitch.

Holofractal variations #10 on one note: for Sarah Alves

Estudo Planimétrico Virtual #1, produzido com 6 patches em max/msp tocando 3 sintetizadores (Korg M1Le, Absynth 5 e Reaktor 5 Carbon) reprocessados no software Holofractal de Transdução de Música e Imagem com a inclusão de granularização em tempo real.

Virtual Planimetric Study #1

Comprovised at a Max/MSP patch called EPpPV, playing 3 synthesizers (KorgM1Le timbre 37-Timp&Bells, Absynth5 timbre 109-I see stars and ReaktorCarbon2 timbre 22-Schonfraublau. The result was post-processed at the Holofractal Transducer of Music and Image, where the file was played simultaneously in 4 speeds (1, 1.27, 0.2 and 0.5) and a fifth stream was live granularized. 

Virtual Planimetric Study #2

Comprovised at a Max/MSP patch called EPpPV, playing 3 synthesizers (KorgM1Le timbre 59-Hammer, Absynth5 timbre 97-Glock and ReaktorCarbon2 timbre 32-The Warmth. The result was post-processed at the Holofractal Transducer of Music and Image, where the file was played simultaneously in 4 speeds and a fifth stream was live granularized.

Virtual Planimetric Study #3

Comprovised at a Max/MSP patch called EPpPV, playing a Korg Micro X synth (timbre GM-01 Acoustic Piano). The result was post-processed by the Holofractal Transducer of Music and Image (another max patch), where the file was played simultaneously in 4 speeds combined with a fifth stream that was live granularized.

Virtual Planimetric Study #4

This is a very strict fugue based on an automated dodecaphonic series and melodies generator. Despite many parameters are randomized by the code, its form follows the rules of a traditional baroque fugue, including a subject, a counter-subject, an answer, their variation on rhythmic stretching and compressing, inverting, reverting, inverted reversing, transposing and finishing with a stretto. 
In this version, the piano timbre came from a Korg micro X synthesizer and the main series was 0 7 4 3 2 9 6 5 1 11 8 10.

Vozes Novo Pinheirinho

First holofractal impromptu, recorded in 2006, in Paris (France), with Imen Tnani's improvised singing on a digital processed live track with transformations on William Borroughs recorded voice and Eufrasio Prates playing an indian bell.
