"If you've got the money, I'd suggest you got a Yamaha QY70 and a Zoom H4 recorder if you want to make music on the hoof. And if you want to sequence stuff in any depth or sample on the DS, you really should check out the excellent NitroTracker. But if you like the idea of mucking about, making little trancey bleepy bits of stuff, maybe just creating elements for a bigger project in your home studio, this is a nice little tool. If you had the patience, you could build something really impressive. I just don't know that I have the patience."
