Howdy,
I use an XP-80 almost exclusively. I've expanded with the Orchestra II, keys of the 60s 70s, bass and drums, and the discontinued dance card. I've made everything from big band jazz, to country, oldies, R&B, hiphop, and Latin. I don't have a way to get it on the net however.
I hope you enjoy creating sounds, as this is where the XP units really shine. I love creating sounds, and downloading patches from the net. I sometimes wonder why Roland didn't create some of these sounds. The sounds they provide in the user banks are pretty boring, I've erased way over half of them with sounds I've made or downloaded.
