organ works

gamut inc compose for the hyperorgan — the pipe organ turned into a computer-controlled instrument. Through MIDI- and networked interfaces every parameter of the organ is driven by algorithm, while the sound is still produced acoustically, in the pipes. This lets us write music no ten fingers could play: shimmering note-clusters, fluttering repetitions and automated register changes that turn the organ into a living synthesizer.

gamut inc’s work with the computer-controlled organ goes back to 2009. The ensemble was founded officially as gamut inc in 2013; from 2018 it carried the practice to organs across Europe and beyond.

a new language

gamut inc write for the organ in overtone structures and dense clusters — stacking partials and rapid micro-repetitions into shimmering, machine-scale masses that no organist could sustain by hand. Register changes become a compositional voice of their own. The result is neither classical organ music nor electronica, but a third thing: acoustic sound, driven with the logic of a machine.

Three ways to play the organ

MIDIfied organs

Where an organ already has a computer interface, gamut inc drive every parameter — keys, stops, swell — directly by computer.

Orgamat (organ-robots)

For historic, non-MIDIfied organs, gamut inc bring their own self-built playing machines: mechanical actuators that operate the manuals and registers from outside. This lets the ensemble perform on almost any pipe organ — not only the instruments already automated.

BLACK SQUARE

In 2025, together with Belgian organ builder Tony Decap, gamut inc developed BLACK SQUARE — a wind-dynamic, modular pipe organ, fully transportable and playable at almost any venue. more →

gamut inc’s organ works on record

Radiating, AGGREGATE editions, 2026

gamut inc’s recent organ release Radiating was featured on Deutschlandfunk Kultur and aired on OrganRoxx radio.

“The initial reaction is one of familiarity: the organ’s monolithic sonic shape has become pervasive in experimental music, filtered through the work of Kali Malone, Sarah Davachi, Anna von Hausswolff and others. Before long, though, things start to change.”
The Quietus

“It’s like plugging Ligeti’s organ piece “Coulée” from the 1960s into a high-voltage outlet.”
Neue Musikzeitung

AGGREGATE – new works for automated pipe organ, Wergo, 2025

For the first two editions of AGGREGATE (2021 and 2022) we commissioned new works for automated pipe organ. A selection was released by Wergo on the compilation AGGREGATE: New Works for Automated Pipe Organ — among them our AGGREGAT #11.

Breath of Seven Breasts, raster, 2025

Breath of Seven Breasts, recorded during a residency in Toulouse on Yves Rechsteiner’s wind-dynamic organ L’Explorateur (built by Tony Decap), was selected for the raster open call sound of europe 2025 compilation.
