  • designed around discrete transistor OTA cores
  • switchable resonance character with optional ‘Solid bass’ behaviour.
  • switchable filter slope: 12 or 24dB/Oct
  • pleasantly saturating input stage and resonance with higher levels
  • linear and exponential FM options
  • envelope and modulation inputs with independent attenuvertors
  • soft-touch knobs and quality hardware (mostly Alps)

  • "After discovering analog synths, modulars and the beautiful original and cloned analog filters of Moog, Korg, Roland, Sequential, and the likes I felt I wanted to try something a little different and see if I could come up with something that sounds unique and musical in its own right, rather than being a retake on proven circuits from the past. Furthermore, I was hoping to overcome dependency on (nearly) obsolete components, and benefit from the quality of modern components.

    The core of the Nucleus contains a newly designed operational transconductance amplifier (OTA) circuit, built from discrete transistors. While there are technically superior alternatives, a discrete circuit excels in providing a warmer and more lively sound.

    Resonance character:

    • Neutral – Classic resonance, reminiscent of vintage 4-pole designs. Inherently with a loss of low-end at high resonance.
    • Q-comp – Similar to neutral, but compensated for loss of low-end. Providing a firm and stable resonant sound, with slightly different saturation character.
    • K-style – The beefiest of all modes, with a thick mid range and fat low-end, and an aggressive resonant sound.
