To be honest, it's like that on almost every keyboard now, these days. The last one which really had perfectly aligned keys which i bought was a M-Audio Axiom 49 2nd gen. I have a Novation Impulse 49, a M-Audio Keystation Mini, and the Arturia MiniLab mk2 (which has the same keys and keybed as the Keystep), and, they're all not perfectly aligned. It's really a minor issue though, especially as the Keystep/MiniLab keys are really great for mini keys in such inexpensive keyboards.
