Mantis Specifications

Duophonic Hybrid-Analogue Synthesiser

• 200 Patches
  * All patches in RAM so can be overwritten
  * Bank A: 100 Factory presets
  * Bank B: 100 User presets (all set to initial patch)
  * Compare function
  * Initialise patch function

• Duophonic with 2 analogue signal paths
  * Mathematically generated oscillators designed by Chris Huggett
  * Analogue signal path designed by Chris Huggett

• 2 Oscillators plus sub-oscillator per voice
  * Sine / Triangle / Saw / Pulse plus additional wave types
  * Shape control and shape modulation input
      - Will create pulse width modulation on the pulse waveform with perfect square
      at the centre
  * Pitch modulation control
  * Octave selects per oscillator
  * OSC 1 SUB follows oscillator 1 parameters

• Oscillator Drift

  * Creates random pitch variations between oscillators

​

• Multi-mode state variable VCA filters with overdrive
