Patch Base has the best Roland D-05 editor and librarian available for Mac and iPad. Edit any parameter, organize patches, create random patches, and more.
A D-05 voice is made up of 2 Tones, each containing 2 Partials. If that's ever felt confusing, Patch Base clears it up quickly. With the Voice Editor, you can see the structure of your sounds and easily understand what's going on:
Edit and organize the 8 User Banks of 64 sounds each stored in your D-05's memory. Patch Base gives you direct access to the banks, so you can organize voices and back them up to files on your device.
