The sound processing in Strange Attractions for flute, clarinet, French horn, and live electronics involves Attractors Library’s MaxMSP objects that are based on iterative equations generating chaotic attractors (Spasov, M. 2015. Using Strange Attractors to Control Sound Processing in Live Electroacoustic Composition. Computer Music Journal. MIT Press. Autumn 2015, Vol 39, No. 3). It consists of nine short movements, each of which involves one of the nine strange attractors from Attractors Library. The pitch and loudness of the acoustic instruments in these composition affect certain variables in the attractors’ equations, thus causing a continuous change at their outputs as follows: a) the computer software tracks the frequency and amplitude of the acoustic instruments; b) the data obtained from the analysis affects some variables in the strange attractors’ equations; c) these variables cause change at the attractors’ outputs; d) the attractors’ outputs drive the software instruments’ processing parameters and thus transform the acoustic instruments’ sounds; and e) there is a matrix-based system that allows the composer to decide which software instruments will process which of the three sound inputs.
