Roland XP-50 Editor and Librarian

Patch Base has the best Roland XP-50 editor and librarian available for Mac and iPad. Edit any parameter, organize patches, create random patches, and more.

The Roland XP-50 is a powerful multi-timbral synth capable of playing 16 parts at once. Patch Base gives you easy editing of every voice and drum parameter inside the XP, enabling you to harness everything this keyboard can do.

Voice Editor

Each Voice in the XP is comprised of 4 Tone layers, each with its own sample, pitch, filter, and amp envelopes, and LFOs. Additionally there is a multi-effects unit, chorus, and reverb. Patch Base lets you control all of it:

Rhythm Editor

Design your own custom drum kits with Patch Base's Rhythm Editor for the XP-50. Only dedicated menu divers would want to do this without a XP editor, but with Patch Base, it's simple. You can design 64 separate drum sounds per kit:

Performance Editor

The Performance is where all the parts of the XP-50 come together. With Patch Base you can easily edit all 16 parts of a Performance, as well as the multi-effects unit, chorus, and reverb:

Bank Editors

Edit and organize all of the patches, drum kits, and performances stored in your XP's memory. Patch Base gives you direct access to the banks, so you can organize patches and back them up to files on your device.
