Voice Editor

A D-550 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:

Bank Editor

Edit and organize the 64 sounds stored in your D-550's memory. Patch Base gives you direct access to the bank, so you can organize voices and back them up to files on your device.
