Kflux looks like a killer patch for Max for Live, a granulator you can drop in for sound-bending effects and, if you’re decent with Max, open up to learn more about how it works or edit to customize for your own purposes. At EUR9,99, seems like a must-buy if you’ve got a copy of Max for Live.


  • Automate parameters on the Live timeline, envelopes thanks to M4L’s functionality
  • Make streams of grains, big clouds, textures, and the like
  • Multimode filter
  • Transposition
  • Static, sequenced, and MIDI-triggered modes
  • Freeze or bounce tracks
  • Unlocked; open, edit, and reuse. GPL-licensed, so you explicitly have the freedom to reuse and modify it. (I think that’s a perfect choice for M4L patches; more on that discussion soon.)

Video overview, plus some sounds via SoundCloud:

I enjoy some of their creative sound demos:

It reminds me a bit of some of my favorite granular patches from Reaktor, like Grainstates.

You’ll need Live 8 and a copy of Max for Live. The French developers promise more releases in future, too. Buy direct:

Those of you more hard-core Max for Live users may know of other, similar devices to check out. I’d love to hear about them, so let us know in comments.

    No, I'm suggesting that the use of a license could avoid confusion. This is really worth a separate post.

    For instance, we're now on Noisepages using for-fee plug-ins which are nonetheless GPLv3-licensed. That way, we know if we do reuse some components, what our obligations are in sharing those changes.

    Maybe GPL or CC isn't the way to go, and they want things used only for personal use. But I think it's best to put something in writing, so that people know what they are and aren't allowed to do, either way. 

    I think it's the same as any other contract. Contracts aren't just for lawyers; they help prevent misunderstandings. I think many creators don't realize that things like the GPL or CC licenses can be useful tools, worth considering, even if ultimately they determine they aren't the best option.

    But that's something worth discussing for all these communities in general, for anyone making M4L patches or code or anything else.

    This looks great, I am n the process of building a similar granular thing, but I may hold off as this one looks pretty complete. In the past few months I have made about 6 or 7 M4L devices that are almost ready for release. A few deal with interfacing with a launchpad (bitcrushing, BP filter, buffer glitching), others are just interesting effects (stereo bitcrusher, freqshifter, delay sprayer)  with randomness and plenty of ways to control it. Shall I pass these along in the next few weeks as I clean them up?

  • are you suggesting licenses to protect max for live patches, peter? i sure hope you’re not.

  • hi PeterJust to give the info that Kflux is released under GPL license :)We are working on new devices, we will keep you updated on future releases…thanks!

    "Kflux" is actually a new scientific "theory of everything" by a norwegian dude that might prove einstein, hawking and the rest of us wrong.

  • Hey K-Devices, your link it doesn't work. For whatever reason, you need the www in front of it. No biggie, just sayin.

  • ops :p

    Cool, locked would be kind of pointless for granular synth – The main draw of choosing this over reaktor or various plugins is learning/modifying. One could probably do something interesting applying granular synthesis to visuals or even information.

  • midihendrix

    P.S. ableton still hasn't come out with a granular instrument? even fruity loops has an awesome one (fruity loops has alot of awesome things though)

  • @midihendrix: Ableton doesn't do granular? Doesn't Grain Delay and the fact that every sample slot has a granular playback mode count? Not sure what kind of instrument you want; I think it makes sense to do that in M4L.

  • midihendrix

    ahh…forgot about that 😉

    neither is a "granular instrument" but yes

  • vanceg

    Real-time input. Gotta have real-time input for me to want to use it in "Live". I like the tabbed UI, though!

    Not to knock this, which I will check out ASAP, but anyone seriously interested in granular synthesis should really check out Density GS. The M4L version is an incredibly deep granular synthesis environment including an instrument plug and a seperate FX plug for live insert processing. It has a built in grainstate sequencer, very sophisticated XY pad control, grainshape editor etc etc … it is an almost ridiculously deep environment all in a M4L patch. I really can't recommend it highly enough. The interface is perhaps a bit daunting at first for those not used to the sometimes somewhat austere aesthetics of max/msp UIs but Density is so deep that it is well worth spending the time getting to know it. Not sure what the developer's current position on the opensource hackability question is though ..

  • right right, just checking peter 🙂 was a bit confused by that license comment.

  • six.fingered.chyld

    reaktor 5….
    just sayin'

  • 23fx

    but a native ableton grain sampler 
    wouldn't hurt by the way.

    polyphonic/multilayers/multisamples/automatable grain settings are not build in possible

    reaktor can but it's a pricey solution,
    so is MFL.
