I briefly had one (didn't check the version), and I almost immediatly did the re-initialisation procedure to get a "factory presets" unit. Big mistake, since it wiped out most of what was in the memory (what the previous owners made up). Most banks were therefore empty, and I was left with too much programming to my liking.
Finally, I didn't like the sounds as much as the Roland M-VS1, so I sold it off the same week.
