Hi, everyone! My girlfriend is a musician who plays the digital piano and can even make up her own music. I want to make a present for her: to choose a good key midi controller, but I am stuck which one is good as the musical instruments are really not my field. I have joined your forum recently and hope you can help me with my problem. I was thinking about this one https://www.amazon.com/dp/B00WU6H78A...yboardpiano-20, learned about it from a review in the Internet. Is this a reliable source?
