CubuSynth Arkakrion
The CubuSynth ARKARION is a fully-featured analog synthesizer voice in a Eurorack module format, integrating digitally controlled signal routing via a “DNA” patch system.
The ARKARION combines the tactile experience of analog patching with the generative potential of randomized patches, all controlled via a single button or external gate signal.
Inspired by a fictional “DNA synthesis” concept, the ARKARION interprets a virtual genetic code to define routing schemes for CV and audio. This allows complex, evolving sound design with minimal patching.
This synthesizer is designed for users seeking a unique blend of structure and chaos, combining traditional subtractive synthesis elements with a digitally modulated signal flow. Whether played from a MIDI source, sequencer, or by hand, the ARKARION delivers a wide range of timbres, from tightly controlled tones to wild and unpredictable textures.
Key Features
- Analog Voice Engine: Includes 2 analogue VCOs with selectable waveforms
- “DNA” Digitally Controlled Routing: A 16-bit randomizer offers over 65,000 unique routing combinations; routing states visualized via LEDs
- Patch Storage: 64 patch slots (8 banks of 8)
- Envelope Generator: Configurable Rise/Fall, loop, or gated-loop (for LFO behavior)
- Modulation:
- Two VCLFO sources
- A Random Voltage Source, gate-triggered
- Filter: Multimode (LP, BP, HP, AP), manual and CV-controllable
- Tape-Style / CMOS Delay: With CV-controlled time, mix, and feedback
- Gene Modification Knob: For real-time morphing of routing (“gene expression”), with CV control
- Internal VCAs: Two VCAs dedicated to modulation strength control
- MIDI Support: Includes MIDI input with pitch CV and gate outputs (via TRS)
- Form Factor & Power:
- Size: 42 HP × 3U (~213 × 129 mm), depth ~24 mm.
- Power draw: +12 V = ~200 mA, –12 V = ~110 mA
