Astra Turbo Quasar is a dual phase distortion synthesizer that 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, atmospheric textures and ambient soundscapes.
Two 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 enter key.
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, decay, sustain and release.
Filter Section: A smooth state variable filter with cutoff frequency, resonance and filter mode to 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.
Low-Frequency Oscillator: The LFO rate and depth modulates various aspects of the audio signal, you can apply effects such as vibrato or tremolo.
Reverb/Ambience: Brings a sense of spatial depth and width to sound, from small to huge sounding spaces.
Loudness: Adjusts the volume (amplitude control).
Dual Delay: 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. Parameters includes:
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 channels. 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: 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.
MIDI automation: 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).
