Free Software Synthesizers

Friction

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

Friction is a physical modeling synthesizer designed to be applicable to a range of emulative tasks, and is suitable for budget foley production or experimental music.

The architecture applies a friction algorithm to a 2nd order mass-spring, modeling the reactivity of surfaces in contact. Two waveguides are used to model the primary resonances of a physical object. The synthesis engine employs 4x oversampling, providing reasonable emulations of sounds produced by friction, such as squealing tires, squeaky hinges and wiping noises.

Modulation consists of three 32-stage envelopes (designed by Chris Kerry,) 4 configurable LFOs and an x-y pad. A group of sends allows modulators and controllers to be assigned to multiple destinations, similar to those used on xoxos’ other physical models such as Fauna and Oscine Tract.

Fragment

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

Fragment is a collaborative cross-platform audiovisual live coding environment with pixels based real-time “image-synth” approach to sound synthesis, the sound synthesis is powered by pixels data produced on the graphics card by live GLSL code, everything is based on pixels.

Fragment is able to produce high-quality fast additive and granular synthesis simultaneously with re-synthesis support, it has many features making it a bliss to produce any kind of sounds or visuals and is aimed at artists seeking a creative environment with few limitations to experiment with, a programmable noise-of-all-kinds machine.

Fragment ship with:

Powerful asynchronous/synchronous granular and additive/spectral synthesis engine.

Additional subtractive/Phase Modulation synthesis.

Complete audio/visuals live coding environment with JIT compilation of shader code.

Real-time, collaborative app.

Distributed sound synthesis, multi-machines/multi-core support.

Stereophonic or Monaural.

Polyphonic (determined by GPU capabilities).

Multitimbral.

32-bits pixels data real-time capture (WebGL 2 only).

Adjustable audio output channel per slices.

Shader inputs (webcam, images, videos with audio analysis, audio files analysis, drawing over textures…).

OSC IN/OUT.

Spectral recording feature of live performances with blend modes, export as PNG and import back feature, export as WAV file (additive only).

MIDI IN support with hot plugging of MIDI devices.

MIDI Multidimensional Polyphonic Expression support (MPE).

Sessions based collaborative features without authentications, collaborate with your friends easily.

Complete documentation.

One of the most powerful real-time image-synth approach on the market.

And more…

Fragment optional independent synthesis program support 32-bit float signal path, band-limited noise, granular synthesis, real-time scheduling for ALSA driver under Linux, multiple outputs, the sampling rate is only limited by your drivers.

Fragment require a web browser with full support of ECMAScript 5, CSS3, WebAudio and WebGL (2 recommended), a dual core CPU with high clock speed is recommended.

Fragment require a good medium-end GPU, it was developed with a NVIDIA GeForce GTX 970 GPU.

Foo-YC20

Foo-YC20 is a free software synthesizer developed by Foo. Available format(s): VST, LV2 for Windows, macOS, Linux.

Foo-YC20 is a physical modelling combo organ synthesizer. This synth is an accurate copy of the Yamaha YC20 organ, including some of the flaws found in such instruments. This project is open source and the processing code is written in a functional DSP language called FAUST.

The organ is available for Linux, Mac OS X and Windows. In addition to a standalone JACK client, there’s an LV2 plug-in for Linux and VSTi for Mac OS X and Windows.

Features:

Physical modelling, no polyphony restrictions.

Two main voice sections.

Switchable bass section.

A realism control to add flaws found in the real organ.

Flaws:

Touch vibrato is not emulated.

Takes quite a bit of CPU power.

FMMF

FMMF is a free software synthesizer developed by de la Mancha. Available format(s): VST for Windows.

FMMF is a 4-operator FM (Frequency Modulation) synthesizer. It came third in the KVR Developer Challenge 2009.

FMMF has 2 primary aims:

Make FM synthesis as accessible and user-friendly as possible.

Use multi-stage envelopes and LFOs to give lots of movement and modulation.

The waveforms, algorithms and envelopes are all shown graphically, with the envelopes allowing dragging of nodes and clicking to change contour. Special attention has been paid to the envelopes to allow you to customise them in many ways, such as the number of stages, the contour of each stage, sustain and repeat points and tempo-sync. There are envelopes for the volume of each operator, the pitch, and the effects section (filter, distortion and delay) all with velocity and key tracking. Further modulation comes in the form of LFOs for the pitch and effects section, with many waveforms including randomising.

For further sound design potential you have a low pass filter, a multi-mode distortion and a flexible delay (with comb delay option). An arpeggiator lets you add even more movement to create rhythmic sequences.

The default preset bank was created by sound designer brian botkiller and shows off the potential of FMMF to make atmospheric pads and leads with lots of movement, big fat bass sounds, funky arps and oddball sound fx.

Features:

4 Operator FM Synthesis instrument with 17 FM algorithms.

11 different waveforms per operator, with note sync option.

7 Multi-segment Envelopes (up to 32 stages) for amp, pitch and effects modulation · 3 LFOs for pitch and effects modulation.

All envelopes can be free or tempo-sync, each stage can have its own contour.

Envelopes can have user defined sustain and repeat points with flexible locking and zeroing options.

LFOs can be free or tempo sync, with 20 waveforms and phase & note sync options.

Each LFO has its own ADSR envelope.

Arpeggiator with 6 modes and adjustable tempo-sync, note length and octave range.

Resonant low pass filter with key and velocity tracking, can be modulated by envelopes or LFOs.

Distortion effect with 18 flavours, can be modulated by envelopes or LFOs.

Delay with comb delay option, size, feedback and damping, modulated by envelope or LFO.

Harmonics can be adjusted from 1 to 256, with limit on frequency beyond Nyquist.

Polyphony adjustable from 1 to 16 voices.

Portamento time.
