Sputnik Modular Multi-Touch Keyboard Controller


The Sputnik Modular Multi-Touch Keyboard Controller is a modular control keyboard, in the tradition of controllers like that of the Buchla Music Easel, that offers 29 keys, up to 4 voices and the following features:


  • 1v/oct
  • “Pressure” CV (measured surface amount)
  • Gate CV


  • Internal and External sync switch
  • Up, Down, and Random modes
  • CV Trigger input
  • Manual Time control control knob
  • Hold


  • Polyphony Mono/Arp or Poly (2,3,4 voices)
  • Octave switch for +1, +2
  • In Mono/Arp mode, CV2 sends CV1+2 semitones, CV3 sends CV1+4 semitones, CV4 sends + 7 semitones
  • In Mono/Arp mode Gate 1 sends every gate, Gate 2 every 2nd gate, Gate 3 every 3rd gate and Gate 4 every 4th gate and can work like a clock divider


  • Touch sensitive location strip with both CV and Gate outputs


  • CV 1 out
  • Gate 1 out
  • Pressure CV out


  • 2,3,4 voice switch
  • CV 2-4 outs
  • Gate 2-4 outs
  • All Pulses out

    1. Eurorack (and virtually any music gear) is already a “luxury”. The price is very reasonable for what it is. Are there cheaper alternatives? Can you build one cheaper?

  1. I’d rather see a new control surface in the style of the kinesthetic input port. Sputnik seems good at cloning Buchla with extra microprocessor stuff, so they could make up for the smaller input surface with cool tuning and routing systems loadable from a menu. I’d much prefer that to generic C major keyboard design…

  2. This is really cheap compared to alternatives. I do not know about this company, but I can sense good build quality here. I dont see why this should or even could be any cheaper, IMO those who cannot afford this really dont need it. Cause if you have the money to build a +3000 plus bucks modular synth, what is 499 high quality controller to that…. It is not a cheap midi keyboard made from plastic, but piece of instrument made to last decades!

  3. modulars don’t have to be that expensive, depending on your skills and DIY and savvy when it comes to buying used.

    however to DIY something remotely like this (probably the TKB) you will spend a couple hundred in parts and an immense amount of time. if you don’t already have a midi keyboard, then a midi keyboard plus a basic midi-cv interface will run you $300 – $500. If you want one of the few midi-cv interfaces capable of four-voice polyphony and arpeggiation (probably MI Yarns) it will run you $350 and on up. the only other pre-built thing very similar to this is the Verbos with runs $700 I think and doesn’t have arpeggiation or polyphony.

    so… this is probably the most economical way to accomplish what it does, including DIY options.
