Temper

Temper free distortion by Creative Intent

Temper is a free distortion VST, VST3, Audio Unit plugin developed by Creative Intent. Compatible OS(s): Windows 64b, macOS.

Temper is a modern digital distortion plugin which combines a rich saturation curve and a unique phase distortion, with a resonant lowpass filter at the beginning of the signal chain and a feedback loop through the distortion stage.

Temper’s phase distortion offers unique harmonic excitement in the higher frequency components of your sound, bringing character and clarity to any element of your mix. And with a classic overdrive and versatile resonant lowpass pre-filter, Temper delivers a modern tone that brings an all new edge to your sound.

This is our first plugin, and the source code is available under GPLv3.

NitrousPD

NitrousPD free software-synthesizer by NOVAkILL

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

NitrousPD is the second part of NOVAkILL’s “Nitrous Project”. It is a Phase Distortion synth with a full subtractive [virtual-analogue] signal path and a wealth of modulation options. Its super-compact UI is designed to maximise workflow without making it too hard to work with, thanks to large, well-spaced knobs and obvious, simple to use minor controls.

Its main features are:

  • SynthEdit’s standard Phase Distortion Oscillator with two wave generators, each offering 7 different waveforms.
  • State-Variable filter with Low Pass 12 and 24dB/octave and 12dB/octave High Pass, band Pass and Band Reject modes.
  • Two ADSR envelopes, both with multiple interpolation modes [slope] with looping on the modulation envelope only.
  • Tempo-synced LFO with 5 modulation destinations [3 available simultaneously].
  • Randomator modulation source for more natural sounding patches.
  • VCA with Mono/Poly modes and Portamento [mono mode only].
  • Extensive routing for velocity modulation and Mod Wheel control.
  • 16-step programmable Gate Modulation source, assignable to phase mod, filter cutoff and volume [trance-gate].
  • New RARP uses the Gate sequence to create random note variations over a user-definable range [0 to 2 octaves].
  • Overdrive effect.
  • MIDI “Learn” eliminates the need for MIDI CC assignments.

Mothman Z3000

Mothman Z3000 free software-synthesizer by Demonic Sweaters

Mothman Z3000 is a free software synthesizer developed by Demonic Sweaters. Available format(s): VST for Windows.

Mothman Z3000 is a 16 voice polyphonic synthesizer that features two Phase Distortion DCOs, two DCWs, and two DCAs. All six feature the famous 8 point envelope section that made the CZ synthesizer so famous.

The Mothman Z3000 also features stereo chorus, noise and LFO just like the original CZ-3000. There’s also an added switchable velocity feature that gives greater expression than the original CZ, and an added analog style filter on DCA2 to give even more sound options. You can also pan the different DCOs to give more stereo fx.

Programming is very similar to the original CZs, the only difference being that on each 8 stage envelope there is a “scale” feature, which acts like a master envelope control to quickly lower or raise the length of the envelope all around without changing each one individually. The original Casio CZ-3000 Manual can be used to understand the concepts behind programming this plug-in.

There are 64 preset slots with 18 presets already created.

Iridesynth’s Revenge

Iridesynth's Revenge free software-synthesizer by NOVUZEIT

Iridesynths Revenge is a free software synthesizer developed by NOVUZEIT. Available format(s): VST for Windows.

Iridesynth is a stereo virtual analog subtractive synth designed to provide “entertainingly unique tones” with fast and simple programming. It is capable of strong classic analog sounds, retro vintage video game arpeggios and other useful traditional tones as well as “futuristic unheard of sounds”.

Iridesynth features Additive Feedback Harmonics, self-modulating LFO parameters, multiple ADSRs, and seven range octave support. It also includes a powerful Global FX section with effects such as bit reduction, stereo flanging, microdelay, stereo reverb, and even psycho-modulation. There are eight configurable effects in all, each with two configurable parameters. Plus, Iridesynth’s GUI allows realtime manipulation of its interface’s color scheme.

Iridesynth’s Revenge expands upon this original concept of an all around “workhorse synth”, capable of leads, pads, and textures. It accomplishes this by incorporating many changes, including:

  • Dual Phase Distortion oscillators replace old Subtractive synthesis ones.
  • Iridesynth’s Revenge uses less than half the CPU power of the first Iridesynth.
  • No more key-to-note latency.
  • Now two forms of Arpeggiator available: Note-Arp / Glide-Arp.
  • Four Waveshapers enhance Phase Distortion capabilities.
  • Completely new Global FX section; includes Comb Filter, BitCrush, Multi-Delays and more.
  • Over 30 LFOs for extensive parameter automation capability.
  • Completely redesigned Iridescence FX section for enhanced GUI alteration ability.
  • Over 100 presets.
  • Completely rewritten very extensive user manual.
