Go nuts – bit nuts – with our handheld patchable analog logic computer



The bitRanger is a patchable analog logic computer that sculpts sonic worlds ranging from data noise to melodic arpeggios. While being a handheld standalone synth, it is also right at home in the music studio. Extensive connectivity makes it so flexible that it can connect to almost anything: CV control its unique sound, sync it with drum machines and sequencers or use it as an algorithmic CV / GATE pattern generator.

Go nuts! Bit nuts!

The patchbay of the bitRanger is a place for exploration where you can simply connect outputs to inputs to see what happens. This can be done methodically or with complete experimental abandon. Go nuts! Battery Power and a built-in speaker make the bitRanger totally portable. Tweak it’s 4 knobs, 8 switches, and more than 100 patch points in the woods, on the beach, on a train, and in the studio.


  • LFO clock oscillator for rhythmical modulation
  • VCO oscillator is synced to the HFO oscillator
  • 4 modes of operation selectable by 2 switches
  • built-in speaker with volume control
  • On /Off switch
  • expansion connector
  • package includes 3 photo resistors – make your oscillators respond to light by plugging these into the Bend socket


  • 118 jumper cable patch points
  • each oscillator has 3 differently slewed CV inputs, sync inputs, rate knob, and bend points
  • Divider Bits section – use clocks at a different speed to create patterns
  • Adventure Bits section adds irregular rhythmical elements
  • MUX 1 and MUX 2 input sections to modulate data loops and waveforms
  • stereophonic output from MUX 1 and MUX2 sections
  • BYTE CV section is R2R DAC converter which takes bits and converts them to CV
  • DATA modulation section witch a switch adds more flavor
  • Utility Belt section adds advanced features
  • Left and Right audio override section

External connectivity

  • 3.5mm stereophonic headphone output
  • Clock Input to sync the LFO oscillator
  • Clock Output with selectable LFO division (2 or 32)
  • CV Output from the BYTE DAC section
  • CV Input for the VCO
  • CV In and CV Out connectors can be routed to dedicated patch points on the patchbay
