CubuSynth ARKARION
Analog synth voice with a randomizable, digitally-routed 'DNA' patch core
42 HP Eurorack module
The CubuSynth ARKARION is a complete analog synthesizer voice in 42 HP whose signal flow is reconfigured by a digital control layer. Two analog VCOs, an OTA multimode filter, a tape-style delay, an envelope, two VCLFOs and an analog random source are all wired together through a 16-bit 'DNA sequence' that a microcontroller can randomize on a button press or gate. The result holds tens of thousands of internal patch variations, plus 64 recallable routings, so one voice ranges from tightly controlled tones to wild, self-evolving textures with minimal patching.
Features
- Complete analog synth voice: 2 VCOs, multimode filter, envelope, 2 LFOs, random source and delay
- Digitally controlled 'DNA' signal routing - a 16-bit sequence reconfigures internal patching
- 16-bit randomizer with over 65,000 routing combinations via button or gate
- 64 patch-storage slots (8 banks of 8) for signal-routing recall
- Two analog VCOs with DNA-selected waveforms and stable 1V/oct tracking over ~10 octaves
- VCO 2 wave-morphing (sine-triangle-ramp) with CV and an auxiliary mixer
- Exponential, linear and thru-zero FM inputs with attenuators
- OTA multimode filter: Low-Pass, High-Pass, Band-Pass and All-Pass, self-oscillating
- Tape-style CMOS delay (40 ms-1.5 s) with CV-controllable time, feedback and mix
- Gene Modification knob with CV for expressive real-time morphing of many parameters
- Envelope with Rise/Fall and one-shot, looping or gated-loop behaviour
- Two VCLFOs (Mod 1 fast, Mod 2 ~4x slower) with rate CV and outputs
