About

Reverse-engineered documentation and tooling for the SysEx protocol shared by the EP series, plus the saved-project format. The author derived it from capture-verified experiments on real hardware and has verified it on the EP-133 and EP-40, with Riddim-only structures flagged. It is aimed at developers building third-party EP tools.
