A Hainbach & Bram Bos collaboration project

Welcome to Fluss, a granular synthesizer and effect processor with a kinetic control interface, designed by Bram Bos and Hainbach.

Fluss makes full use of the touch capabilities of iOS devices to get you as close to the grains as possible. We created it to be both inviting and fun to play, yet sonically rich and full of sound creating possibilities.

You can set it up to process instruments live, or use it standalone to reshape your sound library into a shimmer of harmony and chaos. Play it like a synth or create generative patches that keep changing over hours. It is all in your hands, and you are the modulation.

The way you interact with grains in Fluss was inspired by composer Iannis Xenakis and his ideas on collision („Formalized Music“, 1971).

Multiple plugins: Import, Record or Live Process
You can import your own WAVs (standalone & AUv3 Instrument plugin), Record audio (Record effect plugin) or live-process sound (Process effect plugin) to create anything from drones and granular echoes to moving microtonal audio textures.
Designed for touch: Kinetic Sliders
All sliders and XY pads are linked to a physics model which lets you flick and throw them around. Minimise the friction for endless bouncing motion, as an innovative substitute for traditional LFOs and modulation. There was never a better reason for using a touchscreen for music.
Shimmer Feedback effect
Like a shimmer reverb, except it feeds the processed audio back into the grain engine. This lets you create an endless loop of pitch-shifting spaciousness, turning even the simplest of sounds into massive woolly mammoths.
  • 3 Voice grain engine, each with an independent playhead
  • Filter inspired by the Oberheim Xpander, including its resonant Phase filter
  • Kinetic sliders and pads for playful interaction with the sound
  • Contains a ton of presets recorded and designed by Hainbach
  • Universal design (iPhone and iPad; iPad Air 2 or higher recommended)
  • Custom scales, unquantised mode and even Scala-import for microtonal experiments
  • Use WAVs, record audio or load the app as a live-processing audio effect
  • Real world tested as an instrument in numerous live performances by Hainbach
