Patch Base has the best Yamaha DX200 editor and librarian available for Mac and iPad. Edit any parameter, organize patches, create random patches, and more.
At the heart of the Yamaha DX200 is the voice of the DX7. And you don't have to be a wizard to program DX7 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 am FM patch, and once you do, it's not that complicated.
Beyond the DX7 engine, the DX200 is a groovebox. Every groove is stored as a Pattern, and Patch Base makes it easy to fully customize every part of it:
Patch Base's Bank Editor lets you change and organize the 128 saved sounds on your DX200. You can easily save a bank to a file for back up and storage, and import entire new banks in seconds.
