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 }

One use for this app is to take original compositions and put a unique twist on them. Another is to use your voice (or someone else’s) and warp it into who-knows-what? It is possible to record sounds directly into the app, although I tend to prefer using existing sound files. This thing is a bloomin’ playground! Great for soundscapes, which I’m only now later in life starting to experiment with. I am nowhere near fluent with granular synths, so reading others’ comments regarding improvements and alterations is interesting to me — stuff I never thought of. But I’m going with a win-win on this one — and you can’t go wrong with the price point, either!

Can’t hear the output no matter what. Tried closing the app, restarting my device, redownloading and nothing.

Just for chaos freaks and hardcore droners. I really miss more control, direction of grains, bpm settings stuff on the controls etc. It would have been great for me, if we could go from clean sample sound to something new. FRMS and other plugs made me WAY more happy, tbh. Nothing wrong with Bram and Hainbach, but it's not for me, also not as an fx, which could have been nice. I regret that I bought it 😓

Bram / Hainbach, This instrument is a literal blast to play with and explore sounds you’d never think of to make on your own. I know it’s technically an app, but it’s so playable, so musical. I’m happy to know there’s still iOS Apps being developed utilizing the touch screen format in this fun/intuitive way. It’s how apps should be on these touch screen devices. Well done. I nearly fell off my bed when I shook the app and everything bounced around. Brilliant! Can’t wait to see if another collab comes out! If so, maybe Nuclear Drums? Atomic Loops? I don’t know what that means or what I’m saying. But it’s staying on this comment. If that brings any inspiration then dope! Thank you for this and again, well done! Cheers.

This is a tool to use with other tools as a control surface,a sampler, and a highly intuitive granular synthesis musical instrument... Please keep making your apps. Your designs are Absolutely Amazing!!!!!

This dev keeps making new apps and doesn’t fix or improve previous ones.
