Fully featured Analog Synth voice with digital Control over Signal flow

The ARKARION is a complete analog synthesizer voice, housed in a Eurorack module, with digitally controlled signal routing. It 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.

ARKARION draws its name from two ideas:

Ark: the vessel, keeper of essence
Karion (from karyon): the core, the nucleus of identity

Together, they form the concept of a living vault—an ever-changing essence that holds countless versions of you, yet always remains true to your core, yourself.

You are never the same.
But you are always yourself.
