Free Virtual Instruments

SOOG

SOOG virtual instrument is a free sound bank for Reaktor, by Icebreaker Audio.

S.O.O.G. (Sub Octave Oscillator Generator) is an analogue style octaver effect for Reaktor 5.8+.

The effect produces a fuzzy version of the input signal, by generating a modulated square wave one octave below the tracked pitch. This fuzzy octave can then be filtered to smooth out the tone, or to create synth style sounds.

The effect works best on monophonic instruments with strong fundamental frequencies like bass guitars or clear vocals.

Sonigen Modular

Sonigen Modular is a free software synthesizer developed by Sonigen. Available format(s): Stand Alone, VST for Windows.

Sonigen Modular is a modular software synthesizer which combines the freedom and flexibility of classic modular synthesis with the benefits of a modern software implementation. The user interface is quick and intuitive to use while still affording the sound designer great freedom. The audio processing algorithms are of high quality while still being CPU efficient.

Features:

Sonigen Modular is fully modular, with as many modules and patch cables as you want.

It combines polyphonic voice and static effect processing in one window. That means you can have multiple MIDI notes playing multiple voices, mix them all down to a single stereo stream and route that through a modular effect chain.

It is fast and intuitive to use, almost everything is done in the main module window. There’s no separate schematic / GUI views, no macro modules, no separate FX window. You can see what is going on just by looking at the main window.

Great sound quality. A huge amount of time has been put into developing high quality algorithms. It has very good aliasing rejection in most cases.

It is CPU efficient. This doesn’t mean corners have been cut. It means hand tuned assembly and run time optimization. The audio processing code is dynamically assembled and optimised in real time as you edit and play.

Sonatina Orchestra Module

Sonatina Orchestra Module is a free rompler VST plugin developed by bigcat instruments. Compatible OS(s): Windows.

The Sonatina Orchestra Module puts the Orchestral samples by Mattias Westlund into a single VST Module for greater convenience. The whole ‘Rompler’ weighs in at a touch over 1 gig and since each instrument loads separately it should never take over 250 megs of memory (the choir is big). Most instruments use about 50 megs.

There are 20+ instruments including a soloist for every major instrument except the Viola and Double Bass. There are sections for all the important instruments including the Viola and Double Bass. Articulations include Pizzicato for the string sections and Staccato for the strings, brass and flute sections. There is also plenty of percussion along with a piano, harp and choir.

Sonata

Sonata is a free software synthesizer developed by SoHa Sound Design. Available format(s): VST for Windows.

Sonata is a VST soft-synth for strong single-shot leads and pads. The distinctive character of Sonata makes it adept at strings and lots of simple subtractive sounds, while also specializing in sparkly and glassy mallet sounds, deep basses, and warm and rich mid-range chromatic inventions.

Sonata features two separate but similarly controlled generators, one for the sound’s immediate attack and another for the fundamental tone. Both consist of rich harmonic spectra which are filtered to provide desired overtones. Each possesses its own exponential decay envelopes for amplitude and filter, and its own ADSR envelope.

The output from these is then fed into a little black box—a complex setup of delay devices set relatively for each note that creates a complex comb-filtering effect. This stage shapes the sound, emphasizing desired frequencies and providing richer post-filter overtones, similar to the way an instrument’s body will influence its sound.

There are three global effects: a cross delay, distortion, and a reverb.

Soft Glow Organ

Soft Glow Organ is a free rompler VST plugin developed by SynthIV. Compatible OS(s): Windows.

2.0 Update (4/10/17): 2 extra voices with octave selection added, glide rate knob (active when mono), some knob response adjustments, gui edits, and minor bugs fixed.

Soft Glow Organ is a Rompler that uses samples from a 1960s electric organ and synthesizer-style controls to produce warm sounds with modern effects.

Details: Sample (from my grandparent’s vintage home organ) plays on note hit (sample will play for over 30s). Amplifier envelope, filter envelope, hp/lp filters, reverb, boost (which can be chained after the filters), LFO (tempo-synced) which can be sent to the sample pitch (vibrato), filter pitch, and pan, mixer with an assignable volume knob, and a panel of extra controls (including mod wheel and a fine tuner) hidden under the reverb controls (use the ‘reverb’/’controls’ selector).
