RetroSynth is a web-based platform that provides a curated library of vintage synthesizer firmware, tools for reverse-engineering and understanding this firmware, and a community space for musicians and developers to share their findings and creations. Inspired by the growing interest in reverse-engineering vintage synth firmware and the desire to understand and even modify classic electronic music hardware, RetroSynth aims to democratize access to this niche knowledge. Users can explore firmware dumps, view interactive diagrams of synth architectures, access tutorials on firmware analysis, and even collaborate on projects to create new sounds or functionalities for vintage gear.
