Yamaha DX7 Editor and Librarian

Patch Base has the best Yamaha DX7 editor and librarian available for Mac and iPad. Edit any parameter, organize patches, create random patches, and more.

FM Voice Editor

You don't have to be a wizard to program FM sounds. You just need good controls. Patch Base makes FM easy to work with by showing you the layout of the currently selected algorithm and the envelopes and settings of each operator. You can finally visualize what's going on inside of the DX7, and once you do, it's not that complicated.

Bank Editor

Patch Base's Bank Editor lets you change and organize the saved sounds on your DX7. You can easily save a bank to a file for back up and storage, and import entire new banks in seconds.
