Hel is a simple, universal expander for polyphonic oscillator modules from Xaoc Devices, such as Odessa. It allows to freely control up to five voices of polyphony via individual Volt/octave inputs. For detailed description, please refer to the manual.

  • Five voice CV inputs (0 to 5V)
  • The inputs are scaled in V/oct
  • The inputs are quantized in a chromatic scale (every change of 1/12 V corresponds to a semitone)
Technical details
  • 3hp, skiff friendly
  • Current draw: +20mA / -0mA

Hel is a great companion to the Odessa (sold separately), and other planned Xaoc oscillators.
