Ronan Fed is an independent developer of free VST and VST3 audio plugins for Windows, with a catalog spanning virtual instruments and effects aimed at electronic music producers. Several of the plugins were built using SynthEdit and Flowstone, and the line gained a following in the bedroom-production community for offering capable sound design tools at no cost.

The instrument lineup includes Pneuma and Pneuma Pro (polyphonic subtractive synthesizers with wavetable support, multi-mode filters, modulation envelopes, an arpeggiator and hundreds of presets), Essence and Essence Plus (subtractive polyphonic synths), RF-AB303 (a monophonic synth that emulates the Roland TB-303 with onboard EQ, distortion, compression, delay and reverb), RF-Bassline (a dedicated acid bass synth), RF-Drums and RF-PADS (drum romplers with modern and vintage kits) and RF-Soundfont (an SF2 player). The effects side includes RF-DSP, a multi-effect processor, and AIRE, a stereo hall reverb.

Coverage in outlets such as Bedroom Producers Blog, KVR Audio and Germany's Beat Magazine helped the plugins circulate among trance, techno and synthwave producers looking for free alternatives to commercial soft synths.

Ronan Fed has 2 products cataloged on Equipboard, including Synth Plugins and Drum Machine.
