Read full description

Fluss is a sonic playground designed by Bram Bos and Berlin-based musician Hainbach to let you explore granular synthesis in a hands-on way. The playful touch UI invites anything from live performance, experimentation to learning and mastering the granular concept. 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 - Playable via MIDI (since version 1.1) - Filter inspired by the Oberheim Xpander, including its resonant Phase filter - Kinetic sliders and pads for playful interaction with the sound - Universal design (iPhone and iPad; iPad Air 2 or higher recommended) - Custom scales, unquantised mode and even Scala-import for microtonal experiments - Use WAVs (or other audio files), record audio or load the app as a live-processing audio effect - Real world tested as an instrument in numerous live performances by Hainbach - Offers light mode and dark mode UI
