A Dual Expression Pedal plus Meta-controllers

I just found out about a new product from Pigtronix: the Dual Expression Pedal. An expression pedal with two outputs for controlling two separate parameters (of any of your pedals with expression pedal input) simultaneously. Which I think is just awesome.

In the video below David Koltai controls the blend of a delay’s wet signal and the rate of a tremolo at the same time. Delay comes in as the modulation slows down.

This made me think of an interview I read some time ago (with young artist/developer Tarik Barri published on and a concept I’ve wanted to share ever since: meta-controllers. Meta-controllers basically mean to abandon the idea “that each slider, knob or button should correspond to a single parameter in the software”, or in any circuit or system. In other words, a meta-controller is a single control unit (knob, slider) that you set to modify multiple parameters. Tarik explains:

They [meta-controllers] don’t just control a bunch of single parameters; they control whole ranges of parameters in different ways. Sometimes even one single parameter is influenced by three sliders simultaneously.

The concept behind this is, that as a live performer, I don’t care about the individual parameters any more; I care about aggression, dreaminess, melancholy, the subjective states that I can evoke in myself and the audience. So I want these states to be represented as directly as possible in my use of controllers, enabling me to react intuitively and quickly to the current situation. For instance, my ‘aggression’ slider influences the speed at which all objects move: the shakiness of the camera, the saturation of the colors and the roughness of objects’ surfaces.

Read the whole interview here. And feel free to post your comments below. You may have been using meta-controllers without knowing!


For this edition of our colectivo futurist section, we’d like to introduce the brilliant work of Berlin based, Dutch born visual composer Tarik Barri. We first came into contact with Tarik’s work at the Atoms For Peace London show at Oval Space back in February. There, Tarik had not one, but three screens to wow everyone in attendance with his otherworldly and psychedelic imagery. Needless to say we were amazed and became instant fans. Soon after, we started researching more about the artist and realized he was also behind the visuals of one of the most respected European techno producers, Robert Henke aka Monolake. Fortunately, Tarik was kind enough to grant us an interview in between his other shows for Atoms For Peace and while he was preparing a new project to be shown at Sonar in collaboration with Nicolas Jaar. Follow this link to learn about his love affair with audiovisual composition and programming, his creative process, and his future plans.

Atoms for Peace - Amok

I want to learn to make live visuals a tenth as good as these.

Watch on

Atoms for Peace, Thome Yorke’s new band, has a new record coming out. Here’s a video for the first single, “Judge Jury and Executioner.” Also in the band are (via wikipedia):

Red Hot Chili Peppers bassist Flea (bass), longtime Radiohead producer Nigel Godrich (guitar, keyboards, synths), Joey Waronker of Beck & R.E.M. (drums) and instrumentalistMauro Refosco (percussion). Their debut album, Amok, will be released on February 25, 2013.”

The video by Tarik Barri is relaxing to watch and compliments the music well. I was wondering if the graphics were designed to go along with the music, or if, like in a lot of Radiohead’s work and collaborations, technology played a bit more of a role than meets the eye. After looking up Mr. Barri’s site, it appears he is a master of creating generative software. It’s interesting now that the accessibility of technology like iPads and programming languages like Processing can match the ambitions of content creators.

Last year, at a Pop-up Magazine event, I got to see Scott Snibbe talk about his Biophilia collaboration with Bjork. He is to generative images what Brain Eno is to generative music. Snibbe has been in the game for a long time, and onstage he was just so excited that there is finally a high-quality tablet that lots of people have acces to. He’s been writing software that has been yearning for a platform like that, and now he has it. 

All this is so say that we are at an exciting crossroads of music and technology, and it’s really fun and inspiring to watch as people experiment and constantly push the limits of what is possible. The Creators Project are especially adept at covering this creative activity. 

                                  Decibel Festival Recap - Nicolas Jaar & Friends

It was the third time Mount Kimbie has performed in Seattle in less than a year. I have no idea why we could be so fortunate, but you can rest assured that each opportunity was seized, and each time the two trailblazers that make up the band shattered the expectations they had set previously. Each show has been put on through Decibel, and this time around it was for the annual festival. Going into the Showbox Sodo, it wasn’t as clear for what to expect - they weren’t headlining like they had been in the past. The venue itself is gargantuan - easily twice the size than any previous venue, and is notorious for very peculiar spacing, so there was some initial anxiety before they got on stage. Any and all apprehensiveness was immediately dusted off when Mount Kimbie took the stage. Not only did they play a full length set, but it was the most energetic and enthusiastic performance to date. It was very much a reciprocal trade-off, with the audience giving back just as much as the music put out. A lot of you may have had an opportunity to see these gentleman perform in the past year - especially since the release of their sophomore album, ‘Cold Spring Fault Less Youth’. The style of live performance may not be the first of it’s kind, but the way these guys seamlessly blend the experience of an avante-garde electronic escapade and a four-on-the-floor club scene is truly brilliant. The fans Mount Kimbie reaches is one of the richest in variety, and it’s a result of turning a blind eye to conceptual notion of genre-barriers. What they make, and what they play is music of a new standard and quality that has spread like wildfire. It’s a blessing and a curse to see these guys play, simply because at the end - you want nothing more then to experience it all over again. It should be noted as well, that the slideshow of photos captured on what I assume to be a disposable camera, has been utilized in every set of theirs, and has yet to become dull. Far from it in fact, the visuals are an exceptional compliment to the music. As the sounds and aural emotion vary, the photos stay consistent and surprisingly enough, pair up well with whatever they’re playing at the time. The topic of visuals serves as a great segue to the next performer - Nicolas Jaar

Words will never do this justice. The life-changing experience that Nicolas Jaar provides is one-of-a-kind. There was a unifying presence within his music that every single individual in the audience felt deep within their being. Before we delve into that however, Tarik Barri deserves a good deal of credit for all of it. HIs visuals that were projected during Jaar’s set were by far, the best visuals I have ever seen. From an individual with little to no programming talent whatsoever - the complicated array of images and algorithms that went into the projectoins were present throughout. They were flawless and a sincere joy to watch and move to with Jaar’s music in the forefront. (Here’s a taste of his visuals played in conjunction with an Atoms for Peace performance.)

Nicolas Jaar has an uncanny ability of building a specific tension through out the crowd with the way in which he delays using low ends. From “Space Is Only Noise” he would trigger certain, familiar field recordings and play them out, tastefully mind you, til the point of breaking. And just when it seemed like the rubber band was at stretching capacity, and was soon to snap - he would release his grip on you and put you in this hypnotic trance of a state with his productions in full swing. It was an adventure that you could tell right form the beginning could never be matched again. It was of an entirely different element - incomparable to any other performance due to it’s originality and unique qualities.

A profound night to be remembered by everyone at the 2013 Decibel Festival.
