Key Features:

Synthesis and Sound Generation:

  • Analog Oscillators: Two analog VCOs (Voltage Controlled Oscillators) with waveform selection, including sine, triangle, saw, and square.
  • Low-Frequency Oscillators: Two LFOs for modulation purposes, with selectable waveforms and frequency controls.
  • Filter: A multi-mode filter with low-pass, band-pass, and high-pass modes for shaping the sound.
  • Envelope Generators: Two ADSR envelope generators for controlling the amplitude and modulation of the sound.
  • Noise Generator: White noise source for adding texture and complexity to patches.

Modulation and Control:

  • Patch Points: Semi-modular design with 20 patch points for flexible signal routing and modulation possibilities.
  • MIDI Integration: Full MIDI implementation for integration with other MIDI gear and DAWs (Digital Audio Workstations).
  • Sequencer: Built-in step sequencer for creating rhythmic patterns and sequences.
  • External Control: CV and Gate inputs and outputs for interfacing with other modular and semi-modular equipment.

Interface and Build:

  • Interface: Intuitive interface with clearly labeled knobs, sliders, and patch points, making it accessible for both beginners and experienced users.
  • Build Quality: Rugged and durable construction, suitable for studio and live use.
  • Dimensions: Compact and portable design for easy integration into various setups.
