Actually, it is one of the very few things that I didn't keep long. I preferred a lot more the sounds from the Roland M-VS1! But I didn't change the presets, so there might be more to it that I just didn't see. I havn't seen any for a hundred bucks, so you'll have to keep looking to grab it: mine sold for $160 in minutes, and it was the cheapest one I've seen in 4 years!
