AtomoSynth takes on the desktop semi-modular monosynth format with the KOE-M6 that mixes Moog and Make Noise stylings with some unique features.
It’s interesting how the knobs say “Moog” and the square lights say “Make Noise” and yet the KOE-M6 has a voice all of its own. Designed and built in Lima, Peru this is not the first version of the “KOE” that we’ve seen from AtomoSynth. In 2017 we saw a dual oscillator KOE at the Tokyo Festival of Modular. The new KOE-M6 greatly develops the idea, keeping the vactrol based filters while expanding into other areas of modulation and effects. One interesting decision is to move to a single analog oscillator while making a digitally controlled square wave oscillator available only over MIDI.
Anyway, here are the specs. The analog oscillator has switchable sawtooth and pulse waveforms with pulse width modulation. There’s a square wave sub-oscillator at -1 or -2 octaves. The aforementioned DCO is triggered by MIDI and has its own audio output. The LFO has triangle and square waveforms and the frequency can be voltage controlled. There’s a Random Voltage Modulator with 6 modes including Sample & Hold, random, dust, random gate, pulse and MIDI CC. There’s an ADSR envelope and also a loopable Slope Generator with CV controllable rise and fall. At the end of the chain is a Delay effect with CV controllable delay time.
AtomoSynth appears to be famous for its vactrol based filters which give the cutoff a more organic response, and KOE-M6 has both a high and low pass filter.
The case is made from rugged sheet metal and the whole front panel can come off so you can drop it into a Eurorack system. The patch bay offers 17 inputs and 15 outputs along with a MIDI interface. There’s also a voltage mixer for mixing up your modulations.
Shipping should start from the 1st of February for $449 with free shipping worldwide. It’s a great price when compared to the Mother-32 or 0-Coast and offers something a bit different. The sound demos are excellent and this could be a great synth for someone wanting to explore modular patching or add a lot of functionality to a Eurorack system.
