Mochika X5

EurorackAnalogMonophonic

Imagine a compact powerhouse that squeezes a full analog synth and sequencer into your Eurorack case or desktop setup, handcrafted in Peru with that signature AtomoSynth warmth and grit. The Mochika X5 reimagines the classic Mochika lineage with a fresh triangle-based VCO delivering core and folded triangle waves, paired to a rock-solid digital square DCO that's always in tune, plus voltage-controlled wavefolding for aggressive, metallic timbres that cut through any mix.

Its vactrol low-pass/high-pass filter—AtomoSynth's secret sauce—pairs with an ADSR envelope for punchy, organic sweeps, while a versatile LFO with square and triangle waves adds modulation depth via voltage control. The star is the 16-step sequencer, packing 8 parameters per step like on/off, pitch, dual CV outs (one with random options), gate time, repetition, retrigger, and probability, all tweakable live via 8 push encoders and a crisp OLED display. With 34 pattern memories, 8 play modes from forward/reverse to drunk walks and polyrhythms, MIDI in/out for sync and transposition, plus CV/gate ports, it's a live performance beast in a 48HP/25mm deep module or sleek laser-cut metal desktop box drawing just 123mA on +12V.

Players love its raw, immediate sound—think arcade bleeps meets modern modular mayhem—and the intuitive editing that lets sequences evolve on the fly, though some note the monophonic voice keeps it focused rather than sprawling.
