Atlantis

Atlantis free software-synthesizer by Jeremy Evers

Atlantis is a free software synthesizer developed by Jeremy Evers. Available format(s): VST for Windows 64b.

Atlantis consists of Atlantis Synthesizer, a VST instrument, and Atlantis Filter Delay, a powerful VST effect plug-in.

Atlantis Overview.

3 true stereo morphing oscillators, with independent width, phase, spread, chorus, tuning, volume, envelope and panning feed into a pair of filters (with standard algorithms and many unique new ones), a shaper (distortions and beyond), and a simple room modelling multi-tap filtered delay system with another pair of selectable filters. The routing of the filters and shaper can also be switched into a variety of configurations for further flexibility.

All the standard waveforms you would expect (sin, square, triangle, saw, noise) – and you can also import any waveform you like. Simply add a .wav file with the waveform you want to hear to the c:chips folder – stereo or mono, any samplerate or bitdepth you like, and Atlantis will let you use it for oscillators and LFOs. Samples are upsampled into high resolution wavetables.

Every slider parameter can be controlled by any modulator. LFOs, Envelopes, MIDI Control Data, the current note, velocity, or combinations of them can be used to modulate your sounds into “expressive organic creations”.

The synth also offers selectable Polyphonic, Monophonic, Portamento and Arpeggio modes.

Astralis Orgone / Astralis Orgone Lite

Astralis Orgone / Astralis Orgone Lite free software-synthesizer by Homegrown Sounds

Astralis Orgone / Astralis Orgone Lite is a free software synthesizer developed by Homegrown Sounds. Available format(s): VST for Windows.

Astralis Orgone is a “Dual Sample” based Synthesizer. It is the next generation of the Astralis Range and is highly optimized with great improvements in CPU use and especially load times. It is a rounded synth capable of sounds ranging from Trance Style Rhythms to Hard Leads and excels at Pads, Atmospheres and FX. Great care has been taken into developing a logical layout and many useful control features, such as double click resets and CTRL fine control adjustments. It comes with 128 presets and 150 samples, though you can add your own samples very easily.

Astralis Orgone Lite is the free version of Astralis Orgone with a reduced feature set. It is free, fully functional and a feature packed synth in its own right. It includes 128 presets and the diversity of sound created from 25 samples demonstrates the power of the Astralis System. Great for creating atmospheric Pads/Ambience/FX as well as Trancegate, Modulated and Arpeggiated Rhythms. The synth is free to use but donations are always appreciated to support future developments. More details here.

Astralis Baby Bion is a free software synthesizer developed by Homegrown Sounds. Available format(s): VST for Windows.

Astralis Baby Bion is a free lightweight synth using the oscillator from the forthcoming Astralis Bion. It was designed primarily with SoundScaper in mind, the free FX plugin from Homegrown Sounds, which can create complex undulating collages. Baby Bion adds a synth to create the sound source, as well as flanger/filter, a complex LFO and a couple of 32-stage envelopes. Although it specializes in soundscapes and atmospheres it can also be used as a general lightweight synth. The uniquely developed dual oscillator provides over 3,500 different waveforms which can be mixed in many flexible ways including FM.

Features:

  • Dual Oscillator – The Oscillator provides 2 waveforms which can be mixed using one of the many modes which includes A+B, A-B, Various FM Modes, Dual Pitch, Split and Distorted.
  • Filter – Cascadable up to 8 times and includes Low Passes, Hi Passes, Band Passes, Comb, Low Shelf, Hi Shelf and Peak.
  • 32 Stage Envelopes – Capable of repeating sections; one envelope is for volume and the second is for the filter and general purpose, assigned via the modulation routing.
  • Drive – Auto Volume Distortion
  • LFO – Uniquely developed LFO with standard shapes, plus custom shapes with smooth control.
  • SoundScaper – Comb / delay / reverb effect for creating interesting soundscapes.
  • Flanger/Filter – Switchable between flanger and filter effect, LFO has over 300 predefined shapes with smooth control as well as standard shapes.
  • FX Routing – 3 different paths available.
  • Modulation Routing – Multiple options for assigning modulators to destinations.
  • Stereo Spread – Allows setting a random value to the pan of each voice.

Arppe2600va

Arppe2600va free software-synthesizer by Voltkitchen

Arppe2600va is a free software synthesizer developed by Voltkitchen. Available format(s): VST for Windows.

Based on ARP’s legendary semi-modular analog monosynth, Arp2600va aims to emulate the original Arp2600.

Like the original, it’s a monosynth, but also like the original, it has many Frequency Modulation options which enable it to create some truly weird sound effects. PWM, Sample & Hold, virtual Spring Reverb, Ring Modulation, and a dedicated Noise Generator are all there.

APG Composer

APG Composer free software-synthesizer by dlab

APG Composer is a free software synthesizer developed by dlab. Available format(s): stand alone application for iOS.

APG Composer combines a 3-voice FM synthesizer with an implementation of the Logique Analogique sequencer, which triggers notes when a weighted sum of different signals exceeds a threshold.

The app was created from a Simulink model without writing app-specific code, using the Audio Plugin Generator source code.
