SATOR (Sound Answer To Original Request) for organ and live-electronics (2021)

New Music by Karlheinz Essl

SATOR is an interactive live-electronic extension of my organ piece "tenet opera rotas", based on a computer program written in MaxMSP. It was composed right after the studio recording of the former piece at the request of Pier Damiano Peretti. By using real-time sound processing on the spectral domain, the acoustic organ is transformed into an electroacoustic hyper-instrument which expands itself, opening virtual spaces into the unknown.
