Okay, i think this can be explained by newer devices (mu2000ex) upgrading the xg/gm/gm2 patches, but deliberately leaving the tg300b patches alone, so that the gs midis sound the same. an mu50/80 would sound much closer.

So s-mu2000 now has a fully translated main display. this helps a lot.

It also now plays back a very nice 4 port midi cover of Necrofantasia, complete with all it's display trickery.
