Virtual Synthesizers: Additive, Subtractive, Phase Distortion, FM Frequency Modulation Synthesis VST VST3 Audio Unit (Windows / Mac)
Spherator is a frequency modulation synthesizer to generate an eclectic spectrum of sounds, through a sine wave modulator oscillator that modulates the frequency of a sine wave carrier oscillator, by creating harmonic and inharmonic sounds.

Synthractive is a stereo subtractive synthesizer. Tones are created by subtracting unwanted frequencies, usually harmonics, attenuated by a filter to alter the timbre of the sound. Dialing in a combination of parameters from the oscillators, LFOs, amplitude and filter envelopes, will determine the tone and shape of the sound, which allows to sculpt a wide range of sonic texture.

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. Features a collection of 30 presets suitable for many genres and styles of music and flexibility to custom design over a diverse sonic palette.

Harmodion is an organ and a free-reed aerophone virtual instrument, which includes electronic, clonewheel drawbar, transistor and combo organs, as well as reed harmonium, flutina, accordion and bandoneon. It uses additive synthesis allowing to manipulate harmonically the sine waveform components to produce pitched sounds, as well as to individually detune those components to produce inharmonic timbres. A set of sliding draw-bars are used to mix the various harmonic components generated by the tone-wheels emulation in order to synthesize a wide variety of sounds.
