Hi Dan,
unfortunately I don't currently own any sort of Roland either,
wondering if EMC might be of any help?
I have Universal version. Roland style can be loaded and exported as a midifile. Would the resulting data be of any use?
Unfortunately EMC isn't 100% reliable, it does remove certain controllers. Let me know if I can be of any help.

My last Roland was a Va7, nearly 10 years ago, & my memory ain't what it used to be. haahaa
