Astra Turbo Quasaris a
dual phase distortion synthesizerthat dynamically change the harmonic content of a carrier waveform by
influence of another modulator waveform.It can be used to
create spacey pads, synth keys, leads,
textures and ambient soundscapes.
Features a collection of 30 presets suitable for many genres
and styles of music and flexibility to custom design over a
diverse sonic palette. Available as plugin in VST and VST3 64 bit versions for Windows, as well
as in Audio Unit for
Phase Distortion Oscillators:
Offers 16 different single-cycle waveforms per channel.
Modulation Depth: Controls the
wave shape distortion for left and right channels. The values can be changed
by turning the slider or by entering a value from the keypad and pressing
Waveshaper Section: These combo
boxes presents a double selectable wave
shapes with 5 basic waveforms: sawtooth, square, pulse, double sine and
sawtooth-pulse plus 3 resonant waveforms: resonance 1 (sawtooth), resonance 2
(triangle) and resonance 3 (trapezoid).
Provides independent controls
for the left and right channels.
ADSR Envelope Generator: A four stage envelope generator
with independent control over each stage:
Attack: determines the time it takes for the note to get
to the maximum level.
Decay: determines the time it takes for the note to go
from the maximum level to the sustain level (controlled by sustain).
Sustain: determines level the sound is played at while
the note is held (after the other envelope states, attack and decay, have
Release: determines the time it takes for the note to
fall from the sustain level to zero (silence) level when it is released.
Envelope Modulator: Controls how much the envelope
modulates the cut off frequency passing through the phase distortion
Filter Section: A smooth state variable filter with the
Filter Cutoff: Adjusts the frequency range to contour
the sound, add or regulate brightness.
Filter Resonance: Slightly emphasize or suppress
portions of the signal above or below the defined color/tone frequency.
Filter Mode: Switches the filter between lowpass, highpass, bandpass, or
band-rejection filter types, offering a simple and effective tone control to
shape and color the sound source.
Filter Strength: Makes subtle changes to the filter character:
Stage 1: Tone is slightly attenuated. Provides a warmness tone.
Stage 2: Tone is slightly amplified. Something brighter in character.
Low-Frequency Oscillator: These parameters apply LFO modulation. By
using the LFO to modulate various aspects of the audio signal, you can apply
effects such as vibrato or tremolo.
Bypass: Enable or disable the low frequency oscillator effect. Bypass
switch on, the LFO is bypassed. Bypass switched off, LFO is active.
Rate: Controls gradual changes to the pitch of notes or the filter cutoff
Depth: Controls the amplitude of the LFO. With a lower setting, the resulting
modulation is subtle, while a higher depth will result in a much more
a sense of spatial depth and width to sound, from small to huge sounding
: Adjusts the volume (amplitude
Dual Delay effect: Stores the input
signal and plays it back after a certain amount of time, creating from a
subtle echo to a pronounced blending of previous sounds with new sounds.
Improves the stereo image by adding a slight delay
to one of the channels.
Amount: Controls how much delay is applied to the
signal, which is to be delayed.
Time: Modulation to vary the
delay time dynamically, to control independently the left and right
Time can be changed by turning the knob or by entering a value from the
keypad and pressing enter key.
Feedback: Regeneration of
delay, to control independently the left and right channels. The values can
be changed by turning the knob or by entering a value from the keypad and
pressing enter key.
Mono mode switch: Possibility of turn the
synth into monophonic mode.
Glide: The rate at which
portamento slides the pitch between two notes, when playing in monophonic mode.
property: Tooltip when the mouse is over a control. You can mouse over any of the controls anywhere in
Astra Turbo Quasar and this will display a short description of what that control does.
Implementation of MIDI Continuous Controller parameters for use with
external hardware control via DAW.
Preset Manager: 'Browser' to
load and save presets and banks, enabling to export to *.fxp (VST2 Preset),
*.fxb (VST2 Bank), *.vstpreset (VST3 Preset), *.aupreset (Audio Unit Preset)
plus two generic formats (plain text): the *.xmlpreset (XML Preset) and the
*.xmlbank (XML Bank), providing cross-platform presets/banks. This allows to
control over the loading and saving of presets from disk as well as sharing
presets between different plugin formats using the generic *.xmlpreset (XML
Preset) and the *.xmlbank (XML Bank).
