  • Adjustable oscillators' frequencies, ranging from single frequency to harmonic and non-harmonic series.
  • Oscillators can be purely sinusoidal, or "shaped" by an adjustable parameter.
  • Adjustable attenuation factor between successive oscillators.
  • 30 LFOs, each modulating amplitude of corresponding oscillator.
  • Adjustable LFOs' frequencies, similarly to oscillators.
