The JV1080 was released back i 1994. Stop complaining. Either save up and get a Session Board (which has a good piano), or trash your JV1080 and get a JV1010 which has the session baord pre-installed.

The JV1080 is a great module, but the thing to understand is that the entire Super JV Series (JV1010, JV1080, JV2080, XP30, XP50, XP60, XP80) are all based on that original JV1080 soundset. Either upgrade (Session board goes for $120 + on Ebay), get a sampler (like my Roland S760) or get a new module all together.
