2025-01-19
A vintage synth enthusiast reverse-engineered and rewrote the firmware ROM of the Yamaha DX9, significantly enhancing its functionality to closely match the DX7. By cleverly overcoming hardware limitations and restoring missing features like two additional operators, the hacker enabled the DX9 to load and play DX7 patches. Fixes included improved MIDI handling and a pitch envelope generator. The project's source code is publicly available, showcasing impressive technical skill and passion for vintage synthesizers, even if the target audience is small. This unexpected feat delighted the retro synth community.
