Specifications

4-channel analog VCA, controlled by a digital interpolation engine.

Interpolation engine

  • Up to 64 keyframes, each keyframe storing 4 CV/gains.
  • Per-channel easing curve selection: stepped (no interpolation), linear, accelerating, decelerating, sine, bouncy.
  • Per-channel CV/VCA response selection, from linear to logarithmic.

Inputs/Outputs

  • 4 DC-coupled signal inputs.
  • 4 DC-coupled signal outputs.
  • Global signal input, sent to all unconnected inputs.
  • Internal precision +5V/+10V voltage reference, can be connected to all unused inputs to turn them into CV sources.
  • Global mix output, collecting signals from all unconnected outputs.
  • Frame control CV input.
  • Keyframe change trigger output.

Technical characteristics

  • CV input impedance: 100k.
  • Audio input impedance: 100k (25k for the global input in some configurations due to normalling).
  • Analog audio path, with low-noise/distortion VCA core (V2164).
  • Fastest modulation rate: 15kHz.
  • Cortex-M3 ARM processor.
  • Open-source hardware and firmware.
  • 18-HP.
  • Easy firmware updates through an audio interface.
  • Current consumption: +12V: 90mA ; -12V: 30mA.
