Can you do a SYSEX dump? I doubt the RP12 editor will work with the RP2000. I think they have totally different architectures. I have in the past seen "generic" editors that allow you to build an editor for a specific device.
I believe the latest version works with the RP2K. RPEdit has been continually updated to work with all of Digitechs boxes. It has a drop down menu to choose which one you are using. The bonus is it's a small download and it's free.
