The Filtermate

The Filtermate free filter | ring-modulator by Synthescience

The Filtermate is a free filter and ring modulator VST plugin developed by Synthescience. Compatible OS(s): Windows.

The Filtermate plugin was built as a “Rhythmic Filter Module”, as such it is designed for making automated or non automated filter processing to any given audio material that is fed into it with the minimum of controllers.

Basically it consists on a Clock driver that animates an LFO (Low frequency oscillator) which is coupled to a multimode filter and a mixer, a design very often found on the front panels of many vintage synthesizers, but this time as an independent plugin for you to tweak at your own will.

The Filtermate is fully automatable and has the ability to store 64 presets. It ships with a few already pre programmed ones that will show what its all about and may be the starting point to your individual creations.

Installation procedure: Unzip the file, then copy the DLLs into your VstPlugins folder.

SubRingFM free ring-modulator by Music Unfolding

SubRingFM is a free ring modulator Audio Unit plugin developed by Music Unfolding. Compatible OS(s): macOS.

SubRingFM is a ring modulator. It also has two filters for shaping the sound, plus a sub-octave generator. The oscillator can be manipulated using FM.

The effect runs through a pre-filter to the ring modulator to a post-filter and then into a sub-octave generator. You can use the pre-filter to reduce the number of harmonics in the input signal and use the post-filter to shape the resulting tone. The ring modulator oscillator is an FM oscillator, so the resulting output can be made to contain a very complex set of frequencies. This can then be shaped using the post-filter to get a really wide range of sounds. The sub-octave generator is then applied.

F8-V2 free multi-fx | filter | ring-modulator | reverb | gate | lfo | echo | pitch-shifter by Music Unfolding

F8-V2 is a free multi fx and filter and ring modulator and reverb and gate and lfo and echo and pitch shifter Audio Unit plugin developed by Music Unfolding. Compatible OS(s): macOS.

The Collective 8 Audio Unit Bundle consists of three Audio Units: F8-V2, Mod8 and Res8. All three share a similar amplitude modulation sequence configuration. The audio stream is copied into 8 identical streams and an amplitude modulation pattern can be applied to each stream. The amplitude modulation patterns can be drawn to any shape, with an-easy-to use editing environment that automatically appears when hovering over the patterns with a mouse. Each stream also has filters or effects applied to it individually. The streams are then mixed back together.

The plug-ins:

  • F8-V2 has LFOs, which are applied to highpass, bandpass or lowpass filters.
  • Res8 has a choice of a driven, nonlinear, multi-stage filter or formant filters that can be independently applied to each audio stream.
  • Mod8 has a range of modulation effects like vibrato and ring modulation. It also has echo, reverb, sub-octave, and pitch shifting.

The result is up to 8 different effects running all at the same time, each with its own settings and amplitude sequences. This layering gives unlimited options to create incredibly interesting effects, from intricate and wild effects, to rich, textured reverb, echo, chorus-type effects. The Collective 8 Audio Units come with hundreds of presets. Amplitude modulation patterns can be copied and pasted within each AU or between them.
