Firefly Synth is developed by Sjoerd van Kreel, building upon its predecessor, InfernalSynth, with enhanced features.
It offers capabilities for actual FM synthesis in the style of Chowning, alongside a fully-developed distortion module, a Karplus-Strong oscillator with additional controls, a new CV-to-CV mod matrix, and more.
Firefly Synth supports 64-bit CPUs with AVX and is tested on Ubuntu 22 and Windows 10, with explicit support for DAWs like Reaper, Bitwig, and FLStudio. It’s available for download in VST3 and CLAP formats for both Windows and Linux.
