Roland XV-5050 Editor and Librarian

Patch Base has the best Roland XV-5050 editor and librarian available for Mac and iPad. Edit any parameter, organize patches, create random patches, and more.

The Roland XV-5050 is a powerful multi-timbral synth capable of playing 16 parts at once: each of them either a Patch or a Rhythm kit. Patch Base gives you easy editing of every voice and drum parameter inside the XV, enabling you to harness everything this slim rack synth can do.

Voice Editor

Each Voice in the XV is comprised of 4 Tone layers, each with its own mono or stereo samples, pitch, filter, and amp envelopes, and LFOs. Additionally there is a multi-effects unit, chorus, and reverb, plus deep modulation and control matrix. Patch Base lets you control all of it:

Rhythm Editor

Design your own custom drum kits with Patch Base's Rhythm Editor for the XV-5050. Only dedicated menu divers would want to do this without an XV editor, but with Patch Base, it's simple. You can design 88 separate drum sounds per kit:

Performance Editor

The Performance is where all the parts of the XV-5050 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 the 128 patches, 4 drum kits, and 64 performances stored in your XV'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.
