Roland Corp discontinued support for many of its “legacy” products and my XV2020 has lain unused for some time. However, the internet of things has led me to a program called Patch Base

For the modest sum of around 38 GBP, I downloaded a program that has the same functions as the (now abandoned) XV Editor. It works via MIDI protocol and allows me to recall (fetch function), edit and save the Roland sounds and much more.
The developer has responded promptly to my emails and is working on updates which he says will increase the functionality of the program.
Programs are available for a variety of Workstations and Sound Modules from many developers and I think it’s worth a look for any Reaper users who wish to breathe new life into their legacy products.
I AM NOT ASSOCIATED with the developers of this software.
