After doing a little research, it looks like I'm going to be heading down a rabbit hole for a few days to do this.. So, I'm looking for some advice, hints, etc.
I was amazed how hard it was to find information on creating MIDNAM files. Most of the posts are over a decade old and most of the links for tools, etc. go to dead links or 'click here your computer is infected' screens.

I found a post on the Avid website that was pretty helpful.

However, what I am looking for now is some advice on what is a similar device to the JD-Xi that I can start with to modify. In addition, the 'Roland Patch Script tool' doesn't seem to exist anymore on the Roland Backstage site; at least I couldn't find it.
Does anyone have experience with this process and could provide some hints?
Thanks!
