Hi
I use my JV-2080 in a similar fashion with Cakewalk in my studio.
For every composition I write, I create almost all of the Performance and Part settings right on the JV-2080, then I use a Dump Request to sysex that PERFORM: TEMP +PATCH over to Cakewalk.
This bulk dump is then sent back to the JV once when I open the composition file.
