With the v 2 software many new patches were loaded.
With V2 because of memory limitations there is no room for the demo's, so roland left them out.
You can download the V1 patches at rolandusa.com
V2 Patches are more "loop" and Rhythm oriented.
V1 Patches are more "ambient" "pad" oriented.

(Also note : The manuals still have v1 patchlists, not the v2 patchlists.)
