I bought this keyboard for the minimalist features, the size of the keys and especially for the MIDI out 5-pin socket, not a lot of sub €100 keyboards would have a MIDI out socket so Im very pleased with that feature. the touch sensitive sliders on the side are nice but I would have preferred if they were mod wheels as they would have been more accurate for doing slow pitch rises/falls, the touch strip for pitch isnt very accurate when tryin to do slow rises/falls. The frame is solid metal so VERY sturdy, the keys feel good, not super cheap, they dont spring back too much like a lot of cheaper keyboards and the key spacing is good for smaller hands like mine, I can stretch octaves on this keyboard where as I would struggle to do that on a full size keyboard. ultimately, it fulfills what I wanted - small keys, MIDI out socket, extended range (5 octaves). Perfect for what I need.
