Sun Ra

Sun Ra free software-synthesizer by Elogoxa

Sun Ra is a free software synthesizer developed by Elogoxa. Available format(s): VST for Windows.

  • Dual synthesis architecture. The sound is generated by the conjunction of 1 subtractive oscillator (7 waveforms) and 2 WAV files with samples from real solar sounds.
  • Wave loading option. The users can substitute the 2 internal waves (SOLAR MODES) their favourite .WAV files.
  • Randomization capabilities. The sampled waves (SOLAR MODES) pass through three consecutive note-sequencers (MUSIK, GROOVE and VARIATIONS), which reproduce MIDI patterns that can be combined in several ways. The subtractive oscillator (HELIOS HEARTBEAT) features also its own 3 self-generative modes of randomization, called QUANTA, VOICES and MULTIPLIER.
  • Built in effects. The synth has a bank of selectable send effects, which includes chorus, delay, random and filter, and another 4-Mode filter (Lo Pass, High Pass, Band Pass, Band Reject) completes the signal path after the master out.
  • 3 note polyphonic.
  • Completely automatable via MIDI CC.
  • Includes 24 Factory Presets to give and idea of the potential of the synth.
  • Moderate CPU use (+-20% Athlon 1200).

SubSonic

SubSonic free software-synthesizer by TA Programming

SubSonic is a free software synthesizer developed by TA Programming. Available format(s): VST for Windows.

SubSonic is the synth that takes you back! It’s a subtractive synth that is routed in a way to get that oldskool/vintage sound! However the synth is versatile and powerful enough to be able to create quite strikingly modern sounds when necessary.

Features:

  • 3 Oscillators (Sine, Sawtooth, Triangle, Square, Noise) with detune facilities.
  • Graphical ADSR Envelope for maximum precision.
  • Multiple filter selection: Low Pass, High Pass, Band Pass, Band Reject, and Peaking.
  • High Quality fully customisable reverb module.
  • Delay Module for standard Echo delay effects.
  • Stereo Chorus, to add that vintage depth.
  • The Flanger module is incredibly versatile and powerful combining overall sound of the 3 oscillators and using a sine wave to phase invert the sounds before adding feedback. This can give unearthly sci-fi like textures.
  • The Warper: This module is an envelope modulator, some wacky timbres can be made using this.
  • The Amp! Use this knob sparingly or krank it up and hear that distortion crackle.

SubRingFM

SubRingFM free ring-modulator by Music Unfolding

SubRingFM is a free ring modulator Audio Unit plugin developed by Music Unfolding. Compatible OS(s): macOS.

SubRingFM is a ring modulator. It also has two filters for shaping the sound, plus a sub-octave generator. The oscillator can be manipulated using FM.

The effect runs through a pre-filter to the ring modulator to a post-filter and then into a sub-octave generator. You can use the pre-filter to reduce the number of harmonics in the input signal and use the post-filter to shape the resulting tone. The ring modulator oscillator is an FM oscillator, so the resulting output can be made to contain a very complex set of frequencies. This can then be shaped using the post-filter to get a really wide range of sounds. The sub-octave generator is then applied.
