Sometimes, an idea is so beautifully elegant, it just seems obvious.

That’s the feeling I get from Koma’s newest prototype. The Kontrol Surface is a touch controller device. In its Light version, it’s an X/Y touch controller with CV output. The Pro version adds MIDI so it works with both analog and digital gear, and ups the ante to three-axis X/Y/Z capacitive touch.

Folks with MIDI gear will wait for the Pro version, but the Light edition already appears like it’ll become a must-have for analog/modular owners. Specs:

  • 1 x CV output
  • 1 x inverted CV output
  • Manual gate output (so you can use it as a trigger)
  • Hold function, per-channel, including a momentary hold
  • …and you can clock the momentary hold. (Oh, yeah – so you can do rhythmic effects with the hold feature. It’s subtle how they’re doing this; see their post for a full explanation of what they’re planning.)

Watch a first video demo:

We’ve seen the occasional X/Y touch controller, but typically MIDI-only – KORG’s KAOSS Pad being the only one I can think of off-hand that got wide distribution. Maybe you don’t care about such a thing in the Age of the iPad, but for hardware lovers, it seems perfect – jack in CV to some analog goodies, play.

You’ll see the final versions, they say, at NAMM 2013 at the end of January in California, with shipping end of Q1 2013.

    i have an etherwave plus that has CV output, and i’ve been looking into ways to translate that into a computer as control information. my next step is to maybe build something with max/arduino to process the voltage signal, but anyone have some info on pre-existing solutions (as they’d probably already have signal optimization/smoothing)? what i’ve found so far have been obscure/out of production boxes or components for big modular systems. i thought i’d be able to use motu volta but that looks like it is outgoing signal only.

      Check out Dan Nigrin’s excellent PC 1600 page, especially . The PC-1600 (find on ebay) has two CV inputs, not sure of the resolution, but probably 7bit (midi). I think I heard mention of using the new Moog Minitaur as a CV-to-midi channel, too, in the new version2 software, check out Amos’s latest video at Moog. That’s about all I know of. The arduino idea is fun — just give it a whirl! Using an arduino to generate LFOs, gates at various subrates of the midi clock, is good clean fun, just get one and go. I know nothing about correct buffering of input and outputs, but it seems to work pretty well…(so far).

      cool, thanks kconnor9000. yeah i’ve seen discussion regarding passing the signal through that minitaur, but that’s quite an expensive solution.

  • marcus fischer

    what is that module w/ the backlit knob?! looks fantastic.

    that touch surface is way too small.

    • Peter Kirn

      Will ask what the Pro form factor is like.

  • Chris Stack

    There is so much in my studio I could tweak with this.

    Ach du liebe I love this. I’ve been wanting an xy pad that could handle cv for the longest time …or maybe just since the end of the demo vid …either way. My Monotribe and Moogerfoogers perform best with cv, I think they even sound better with electricity pulsing through them. Im sure the Expert Sleepers stuff and an iPad could give me an XY of cv if I took the time, but I’d much rather have a little piece of hardware just like this. Teutonic minimalism is super toll and super sexy, and I’m sure this sensible young man in the video will see to it that the unit will be sensibly priced. Gimme, bitte!

    So basically a Kaoss Pad Mini or Kaossilator 2
