AtomoSynth Intros KOE M6 Monophonic Analog Semi-Modular Synthesizer

AtomoSynth has introduced the KOE M6 Desktop Edition, a monophonic analog semi-modular synthesizer.

The synth is internally normalized, so you can use without any patch cables. It offers a 32-point patch bay, so you can override default routings. It has a MIDI to CV converter, so you it plays well with standard MIDI gear. And you can use the patch bay to integrate it with other modular gear.

The developers note that the KOE M6 desktop edition can be a great entry gate to the modular world, or you can take the module out of its enclosure and install it in another Eurorack case.


  • Voltage controlled oscillator with saw and pulse waveforms.
  • Pulse width modulation controllable by voltage.
  • Square wave Sub oscillator with -1 and -2 octaves selector.
  • Digital square wave oscillator DCO (controlled by midi only).
  • Low Frequency Oscillator with triangle and square waveforms and voltage controlled frequency.
  • Random voltage modulator with 6 modes (S&H, random, dust, random gate, pulse, midi cc out)
  • Classic AtomoSynth Low pass and High pass voltage controlled vactrol filter.
  • Slope generator with voltage controlled rise and fall times and loop/gate selector.
  • ADSR type envelope generator.
  • Flexible built in Delay effect with voltage controlled delay time.
  • Voltage mixer with gain and positive or negative offset control.
  • Patch bay with 17 inputs and 15 outputs.
  • Midi interface with CV pitch, gate and CC outputs.
  • Rugged sheet metal enclosure finished with micro textured electrostatic paint.

Pricing and Availability

The KOE M6 is available now to pre-order for $449 USD.

    1. They’re easy to design and the semi-modular form factor is really popular right now. It’s a nice balance between the affordability and compact size of a basic analog monosynth and the flexibility of a modular (without the cost of case, power supply, MIDI to CV and a handful of $200+ modules).

      1. 50 years ago the internet did not exist

        its not 50 years ago anymore

        thats why your comment is entirely irrelevant

        checkmate ?

    1. Perhaps some of us have lots of synths and can see this fitting into our setups as an add-on. The greater issue here is people haven’t caught on that heavy inflation is real and your pre-inflation pricing is not coming back.

  1. The redundant nature of this synth aside, just peruse the various sites and they have gained a rather dubious reputation for terrible support, unprofessional behaviour, and poor quality control.
