Hey People, I have the cable in spite of the reviews ordered here times. (One kanns always send back ..) Delivery fast and well packed, as usual in Amazon Prime. The cable is used to connect the keyboard to the laptop and here to use the program Synthesia. If you put the cable correctly, so it is recognized as a MIDI to USB, but does not work so. And here comes the Clue: For recessions other cables someone has given the hint to exchange MIDI in and out, then the cable was working. And, well as Look, it works well with this cable! Conclusion: Little money, works flawlessly and without noticeable latency, you just have to connect "falschrum". Can recommend it!
