This new compact modular Synthesizer looks great and easy to use. Bastl Instruments and Casper Electronics join forces and announced the release of the bitRanger: handheld patchable analog logic computer. The idea looks interesting and demonstrate that modular Synthesizers can be also very small. I have not yet an idea how it sounds in my ears or how easy or complicated it is to patch. Hope I can get my hands on it soon. 

Bastl Instruments introduces a new product at the Moogfest: the bitRanger designed by  Peter Edwards a.k.a. Casper Electronics who moved recently to Brno, Czech Republic to  join forces with the Bastl crew. The bitRanger brings together the legacy of the previous  products debuted at Moogfest ­ the Werkstatt and the Pocket Operator and bridges both  realms of these instruments together.

The bitRanger is a patchable analog logic computer which 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.  

The patchbay of the bitRanger (in the same style as the Werkstatt)  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 rhytmical modulation
  • VCO oscillator is synced to the HFO oscillator
  • 4 modes of operation selectable by 2 switches
  • built in speaker with volume control
  • 9V DC center positive power supply input
  • 9V battery compartment from the bottom
  • <20mA power draw on headphones, <60mA with speaker (minimum 20 hours on battery)
  • 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 different speed to create patterns
  • Adventure Bits section adds irregular rhytmical 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 flavour
  • Utility Belt section adds advanced features
  • Left and Right audio override section


  • 3.5mm stereophonic headphone output
  • Clock Input to sync the LFO oscillator
  • Clock Output with selectable LFO division (2 or 64)
  • 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
