In French cooking, there’s a sauce base called a roux (pronounced “roo”) that is the foundation of bechamel and other sauces. This is a sequencer macro that is the equivalent for programming sequenced instruments in Reaktor – you can take it in any direction from here. In its most basic form it can send velocity information to trigger percussion, or modulate instrument parameters like cutoff and resonance. With a few simple changes it becomes a pitch sequencer, suitable for use in something like the Frankenloop device.


I decided to teach how to use the roux step sequencer before diving into the guts of the Frankenloop because understanding this will make that much easier to untangle. Besides, this is a more modular-ready macro, easily popped into anything else you happen to be building or toying with – like the granular delay we’ve been working on. Anything that could use some sauce, really.

In part one, we look at two uses of this versatile basic ingredient. Download the ensemble and follow along with the video tutorial.

In part two, we’ll study the internal structure of the roux macro and look at some more uses for it.

    Thanks for these tutorials and macros, very useful. After searching around endlessly for plugins that do exactly wanted I decided it was time to bite the bullet and buy reaktor, and just try to build them myself. These are definitely useful in getting over the beginners hump.

    Hi Chris. Since you already have ideas about what you want to do with Reaktor, I think you’ll find it easier to learn. It’s good to have a goal in mind as motivation. What kinds of contraptions are you looking to build?

    Nice colors :)

    I’ve liked bright colors for Reaktor instruments since about a year and a half ago when I was using a neutral putty-blue theme that I thought was serene and restful on the eyes. Got totally sick of it one day and went for bubblegum colors. You’d be surprised the difference it makes in your approach to music.

    Ah, but you’re the guy behind Brick, Jordan? Then I don’t need to lecture you on the importance of interface design. :-)

    Once you go bubblegum, you don’t back, :)

    Like making food or deserts, appearing and interface design definitely make it taste better, or sound better.

    Owen (the other half of Brick) and I think about this a lot with Brick. We realized out first table sort of subconsciously looks like a giant iPod. Soon we will release pictures of the new interface, code named Brick 2.0, and this time, we went for something a little different.

    Maybe one day we’ll have a bubblegum colored touch table and plop it in urban outfitters, next to a bunch of psychedelic Nikes :)

    For now I’ll get my fix by looking at your nice reaktor patch…

    Hi Peter Dines,

    Thank you ever so much for posting these little reaktor golden nuggets :)

    I have a question slightly unrelated to this post. How do I play an entire loop inside beatslicer? Is that possible?

    -Apologies in advance for the silly question :)

  13. Morpher

    -ie is there a way to hear the loop playing through together with the modified slices? (Like in ReCycle, for example) I can’t seem to find ant documentation explaining this…

  14. Peter Dines

    Hi Morpher – unfortunately no, I don’t think there’s a way to do that with Beatslicer. You’d have to manually lay out the notes sequentially in a host sequencer.

    Instead, check out the L3 ensemble. It might be more what you’re looking for.

    Also, if you happen to have Kontakt, it can either play through the loop or map slices to individual keys, and allows you to drag MIDI to the host with properly timed beats.

  15. Morpher

    Hi Pete,

    Thank you for the prompt reply.

    -That’s a shame as I really like the things one can do with individual slices in beatslicer. Oh well… I do realize that it’s mainly a live tool and yeah, you are right, I can do a similar thing in Kontakt. Oh by the way I have instantly fallen in love with HaasCheezburger!! Very handy! :)

    I’ve been using Reaktor for 5 years.
    Built some simple synths.

    Never could figure out sequencers.

    Excellent tutorials here.

  17. Peter Dines

    Thanks Mike! I’m very pleased with how this sequencer tutorial series has been received and hope that it encourages people to push beyond the synth building and start creating things that have behavior as well as sound.

    I’m not sure I know what to say. I want to thank you for dedication and your art. I saw you this evening in A Wink and A Smile and I am completely moved. That movie has inspired me to research creating a burlesque show in Portland! Your Picaso performance was absolutely and truly breathtaking. Thank you.

    Hi Peter
    In case you’re still getting notified, here’s a really basic question: I added a .wav file to the roux-demo, but it doesn’t loop, just plays once. I can’t find any controls or settings that look different on mine compared to the adagio loop it comes with… Help?


  28. David Coffin

    Oops; found it! (gotta switch to waveform view in the sample editor)

    Thanks so much for this, Peter!

    Is there a way to create five hard-wired drum sequences that one could pick from a list in the ensemble itself, without using snapshots? So in other words, one could select a different sequence without changing the instrument’s snapshot? Thanks
