Fuzzed

Fuzzed free distortion by Fuzzed

Fuzzed is a free distortion VST plugin developed by Fuzzed. Compatible OS(s): Windows, macOS.

Fuzzed is an analogue modelling distortion plugin, using “state of the art” state-space modelling techniques to model the physical circuitry of the famous Jimi Hendrix guitar pedal and implement it as a VST plugin using the JUCE API.

Rather than simply modelling the general behaviour of the pedal, this plugin uses the circuit schematic to construct a highly accurate simulation of the pedal’s behaviour, with full parametric control. This is then implemented as a VST plugin for use in real time.

Included are some analysis screenshots of the comparisons between the output of the system and the real pedal, which shows the behaviour of the VST to be highly comparable to the real thing.

This work is the result of continued development of a plugin created and submitted as part of an individual university project.

The examples show case the guitar tones produced, with an additional example showing the use of Fuzzed to add analogue distortion to a synth + verb as a return/aux effect.

Use of Fuzzed as a return effect can add beautiful analogue distortion to your sounds without losing the original tonal content.

**Update 14th December 2016**.

Added Windows 7 support.

**Update 2nd April 2017**.

Optimised performance on some machines. Changes to the circuit to improve the quality of the sound (especially for low frequencies).

Free Amp

Free Amp free amp-simulator by Blue Cat Audio

Free Amp is a free amp simulator VST, VST3, Audio Unit, AAX plugin developed by Blue Cat Audio. Compatible OS(s): Windows 64b, macOS.

Blue Cat’s Free Amp is a free guitar amp simulation plug-in.

Using the same modeling technology behind the “Destructor” and “Axiom” software, Blue Cat’s Free Amp offers 3 amp models for a wide range of guitar tones: the plug-in can produce pristine clean tones, subtle crunches or heavy distortion depending on the amp model and the settings dialed with the guitar-friendly tone controls. It includes two dozens of factory presets to get started, and additional free presets are available for download on the editor’s website.

The plug-in is available as a free download on bluecataudio.com. It is 100% free and does not require any registration or dongle to run without any limitation.

Main Features:

  • Free guitar amp simulation plug-in.
  • 3 amp models inspired by legendary amplifiers: “classic clean”, “classic drive” and “modern drive”.
  • Simulations based on the Destructor dynamic distortion and amp modeling engine.
  • No latency.

Foo-YC20

Foo-YC20 free software-synthesizer by Foo

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.

Flower Child Filter

Flower Child Filter free filter by Soundemote

Flower Child Filter is a free filter VST, Audio Unit plugin developed by Soundemote. Compatible OS(s): Windows 64b, macOS.

Flower Child Filter is the first in an upcoming series of boutique analog-style filters (See FMD). Flower Child is aptly named for its goal to have a clean and resonant sound. There is also a switch for an aggressive growling version that is sure to cater to your more destructive side:

  • Oscilloscope in center of interface to see realtime how the filter is affecting your signal.
  • Self-oscillating resonance.
  • Warm tube-like overdrive by setting resonance to 0 in clean mode.
  • Clean/Aggressive mode where aggressive mode responds well to loud inputs, creating pleasing warmth, overdrive, and distortion.
  • 2 Envelope followers, one for filter, the other for amplitude.

Felix

Felix free software-synthesizer by Kriminal

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

Felix is inspired by the Octave Kitten hardware synth from the early eighties. The really powerful area of the Kitten was the modulation – the LFO / Sample+Hold routing to modulate the ADSR / VCO / VCF – it could produce many interesting effects and S&H sounds. Kriminal tried to capture this in Felix, as well as making it versatile in the normal spectrum of sounds.

Features:

  • 1 VCO (saw/tri/pulse) plus white noise generator.
  • 1 LFO – sine/square/S+H.
  • 2 Sub Oscillators : square (-1 and -2 oct).
  • VCF – 4pole LP self oscillating filter.
  • VCA – ADSR.
  • 200+ Presets.
