Astralis Baby Bion

Astralis Baby Bion free software-synthesizer by Homegrown Sounds

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.

ALIQUOTER

ALIQUOTER free software-synthesizer by milomil

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

This is an aliquote simple synth built from 6-aliquote tuned oscillators. It is an additive/subtractive synth, but oscillators are tuned to aliquote intervals. If aliquote interval is integer, the oscillator is tuned to standard harmonics. Aliquote intervals are typical to natural sound and first instruments (woodwinds, fujara, koncovka, natural drums, …).
