User Reviews

  • Very very good interface for Roland GR55

  • I love this program but, What about an update. Especially for the design and usability.

  • Perfect! Amazing!!!

  • It's criminal that Roland does not underwrite development of this application. Absolutely the missing piece for any serious GR-55 user.

  • Fantastic program. So easy to use. It really allows for some experimentation with the patches. Don't like how it sounds, don't write it. Thank you for your willingness to continue this project and sharing your expertise.
