Hey. I bought it half a year ago. S61 MK2 I use it just for training on the piano using Cubase. My first MIDI keyboard=)
Looks very decent. high-quality plastic coated with matte black paint, the buttons on the control panel are very pleasant to the touch, and have a backlight that does not hit the eye. Work responsive.
Knobs nice and very accurately work when setting any parameters or recording automation, as well as when you touch them from above(have sensors) - show other parameters.
2 display on which all clearly visible, you can configure the brightness, when setting to 100% they are very bright=)
Komplete Kontrol the provides a huge amount of content to create music - personally, I really like "a Gentleman" and "Massive".
Keys with aftertouch - the possibility gives to creativity of ideas=) the keys of very nice material very quiet and have a pleasant sound when you press or just touch.
LED GUIDE is a cool feature.
For six months I have 2 times updated the firmware MIDI keyboard. and also very often go out on bug fixes any products from Native Instuments.
Recommend!
My first MIDI keyboard - which I really like.
