As a workhorse midi keyboard and controller its great.
The keyboard feels very nice and all other hardware too except for the sliders, they feel a bit cheap.
The two problems I have are that the sequencer is really cumbersome to use. Really very much designed for people playing 4 beat loops that are locked 100% to the grid. With a bit of perseverance you can work it into an okay workflow, but overall its uninspiring and does not lend itself to live use at all. I really hope they improve it with some updates.
The other is the Novation Components sofware/web app. This is also an overly basic piece of software that does not match the price point of the keyboard at all. Really frustrated by this. Feels like somebody telling me to build a house of cards with one hand tied behind my back.
For those interested in the CV capabilities, I've found they work quite fine. The midi-cv clock conversion is rock solid and the pitch tracking works fine.
So in conclusion, if you're wanting a studio control hub it's great. If you're wanting a live performance tool, it's still one of the best options, but don't expect much from the sequencer.
