About this project
Overwriting the FM-1's presets with DX7 banks replaces them, and the onboard factory reset only brings back whatever you last imported. The project offers another route: send these four files back with Dexed, PocketMIDI or a similar SysEx tool, with no updater or firmware downgrade.
The tutorial starts from a single sine wave and was checked against firmware v15.
