you're last guess is right. I'd just bought a xp-30 and a week or so later I hear Roland's releasing the new XV series. this has been my first oppurtunity to check out it's sound. I don't perform live or anything so I don't really need the keys. the 'polyphony' of 128 would be welcome though but the xp-30 has a way larger soundset. but the post was mainly done because I was most curious of it's sound.
