I needed a new midi controller. My Novation SL61mKII is past its prime, so I took a look to see what was available in my price range. I wanted a Fatar keybed, and this was the least expensive option for a 61 key controller. After asking about this keyboard to some friends, I was told that NI is fairly abrupt in ceasing support for the software that controlls this keyboard. As Thomann seems to be clearing the mk2s out to make way for the already available mK3, it made sense to determine the limitations of this unit. I am on a Mac, so every year there is an OS update, and sometimes these updates break things, and sometimes developers cease to release new versions to keep up with the OS changes. That is what I've been told will happen with this unit, probably within a couple of years. After NI stops official support for this product, I will have to be careful with my MacOS updates if I want to keep the integration software working.
That is just a point of consideration for anyone considering this model.
The Komplete Kontrol software is the key to this ecosphere. Installation was easy (worst part was downloading stuff @1.7 mbs/sec).
I cannot help but think the software's potential is under-explored. NKS libraries vary in what they will let you do on the keyboard. One of the main things it does is present presets on the keyboard for a given instrument, but some instruments don't offer their presets on the keyboard, so be aware of that.
The filtering system is also a bit clunky. I can't just access a particular collected instrument, rather have to sort by patch characteristics, and that could be better.
Further, many of the parameters that are shown to be available for modification do not adjust when the knob is moved.
They keyboard itself is excellent, no complaints. Integration with Logic Pro was simple, but limited.
I would buy this keyboard again. I recommend it, but be aware of NI's history of canceling software support.
