Two downsides: semi-transpose feature is only available when using the Komplete Kontrol software, which has a steep learning curve; and the light bar feature, as useful as it is, does not have "fun" capabilities, like when pressing a key, the colors shift outwards in a rainbow patterns...this would be cool, but is not available.

It's very cool, and, though not *entirely* necessary, does make things easier and more seamless

i noticed on NIs website that the keyboard does not work well with Pro tools, most of the functionality is stripped
