Noises is an experimental instrument with a playful and inspiring interface, designed to bring a vast world of noise into your music and audio production. Available as AUv3 and Standalone. Noises is the fourth plugin we developed together with German composer and “that guy with the sweaters” Hainbach. He crafted hundreds of recordings of rare vintage measurement and tape equipment, analog synths, strange field recordings, electro-acoustic and magnetic field experiments, and more in his lab to create this creative noise instrument with us. It is designed to be fast and inspiring to use, with a big dial at its center inviting you to search for sounds and a sequencer to make them music. This results in a minimum of clicks for a maximum of sound.
