Recently purchased a DW8000, looking for dedicated utility software or patches. Is the Kid Nepro expander worth it?

Most universal sys-ex librarians support the DW-8000 as well.

I'm unaware of a Kid Nepro expander other than patches. Angel City Audio used to have a mod which allowed split keyboard, random LFO wave, and some fun MIDI stuff a while back which was pretty cool. I don't know if they still do.
