A semi-modular CLAP and VST3 synthesizer plugin. This is basically InfernalSynth’s (https://www.kvraudio.com/product/infernalsynth-by-sjoerdvankreel) big brother.
V1.0 is a very bare-bones release. It does not do monophonic mode yet, and there is no fx-version of the plugin. Other than that, it is fully-functional, and exceeds InfernalSynth’s capabilities in many ways.
See the github page https://github.com/sjoerdvankreel/firefly-synth/ for system requirements, and see the feature list https://github.com/sjoerdvankreel/firefly-synth/blob/main/feature_list.md for a basic feature overview and sort-of manual.
ATM there are also no presets, however there are some host-test demo files you can check out: https://github.com/sjoerdvankreel/firefly-synth/tree/main/demos.
