MINUS is a 1-hour composition for two pipe organs and one digitally generated stream of audiovisual information. The visual stream is presented as a 8x11 meter front projection. The electronic sound partly displayed by multiple numbers of small obscured loudspeakers and at its low end powered by a battery of subwoofers engulfs the person rather than creating distinct sound events at localizable positions.

MINUS was especially designed for the grand hall of the Konzerthaus Vienna, a place not only known for its history, architecture and superb sound but also for its huge pipe organ. The Konzerthaus organs wall of apparently countless pipes looks as impressive as the array of five keyboards and one pedal. MINUS can also be adapted to any venue with a pipe organ which is MIDI controllable.

Although music for organ is usually connected to and determined by the interface for the performing musician, which historically is the keyboard, this interface does not have to be the only way to access the sound producing pipe works. The Konzerthaus organ is fully MIDI controllable. MIDI means to think and access the sonic potential of the pipe work without thinking for a performing musician.
