I was trying to choose between this and the MPK 249 midi controller and was completely happy with my choice. The metal body feels strong, the appearance is fantastic especially when it puts on a light show!
Plenty of control features like chord mode, key transposing, DAW controls for Logic and Ableton (and others) and all the I/O that I need.
The pads are comfortable and responsive, the sliders and rotary knobs work just as needed. The software integration with Analog Lab, Pigments and other Arturia software is smooth and great for workflow.
Arturia are also a great company that I'm happy to support. Their software and hardware products are all quality and their support team is a great help if you need it.
Cons: The keys on mine are a little noisy (getting a spring sound from the keybed). Aside from that, no complaints. This issue doesn't affect my playing or the feel of the keybed.
