Astralis A and B oscillator Info

Astralis A is the Oscillator based Synthesizer from the Astralis VSTi Pack and uses a Dual Oscillator for Synth 1 and a Spectral Oscillator for Synth 2, which is swappable for a second Dual Oscillator.

Astralis B uses the same system but has a single filter and a slightly reduced feature set with the aim of being lighter on CPU usage.

DUAL Oscillator

Uses 2 Oscillators with a variety of mix modes and is capable of a wide array of sounds.

OSC A/B: Selects the wave type between:

  • Sine
  • Saw
  • Ramp
  • Soft Ramp
  • Peak Ramp
  • Square
  • Triangle
  • Peak
  • Octava
  • Cluster 1
  • Cluster 2
  • H-A/H-B: Selects the number of Harmonics the Oscillator Uses.

Mode: Selects the interaction mode between the 2 oscillators between:

  • Single - Wave A only (standard mode)
  • Dual A+B, Dual A-B: PW controls phase of both waves
  • Dual Mix: PW controls Mix between waves A/B
  • Dual Width A+B, Dual Width A-B: PW controls phase difference between waves A/B - Can be used for Pulse Width Mod using Saw/Ramp waves
  • Ring Width, Ring Width+A: Ring signal = A*B : PW controls phase difference between waves A/B
  • Phase Distort: Wave B distorts the phase of Wave A: PW controls depth of phase distortion


  • Spectral Oscillator

    The Spectral Oscillator uses 16 Individual Sine Waves to produce Harmonics, each harmonic level can be adjusted or modulated to create a sound wave.

    SMOD: This controls the Spectral Modulation Volume. To Modulate use S Mod as destination in the Modulation Matrix.
    Spectral/Dual: Switches between the Spectral Oscillator and a Second Dual Oscillator.
