The Fokker organ housed in Muziekgebouw’s Recital Hall becomes a canvas for Marcin Pietruszewski’s generative installation Distortion Product Lattice (Fokker QDTS Wavepackets), commissioned by Sonic Acts. Combining the computer-controlled microtonal organ, digital sound synthesis, pluriphonic sound, and light choreography, the work stages formal and auditory modulations. The QDTS (Quadatric Difference Tone Spectra) algorithm utilised by Pietruszewski produces particular kinds of auditory distortion product (ADP), creating a new experimental approach to generating complex spectra.

Commissioned by Sonic Acts (2024) 
Premiere at Sonic Acts Biennial 2024
