We start with the value of the product. It is definitely worth its money.
User-friendly, lightweight construction, its screen is small but anyone who wants a bigger one can go for €300 and get the next model.
The potentiometers it has work with the touch of the hand and display on the screen the parameter you are handling (very practical).

I bought it to replace the Novation Launchkey MkII because I exclusively use software instruments with NKS protocol and NI Komplete.
The endless encoders have been a great help in parameterization and its ergonomics are simply excellent.
Its truly exceptional quality for its category (keys, knobs, etc.) and the ARP function, which was missing from the Launchkey (although it is available in the more expensive MkIII), are its advantages.
It lost the 5 stars for 2 reasons:
1) To find the latch (hold) of the ARP, you have to enter the ARP Edit menu every time, which becomes tiresome - there is no separate on/off button.
2) At this price, I would have liked either some pads or a larger screen (completely personal preference)

There is nothing better in terms of quality and value for money. The value of the software licenses it provides is greater, making it an excellent purchase... It is the ultimate tool for Ableton/Machine/Komplete Kontrol, etc. etc...
