About

A community sample tool for the EP-133 K.O. II (with support added for the EP-40 and EP-1320, including 128MB units). It handles custom sample import, custom pad colours and names, and backup/restore, and was one of the most popular early community tools for the EP line. Note: the repository was archived in 2026 and is no longer maintained, but the released builds still work.
