hi I am thinking of buying my first midi keyboard for my studio and I really like the Alesis vi61 in terms of looks and features. for midi I would preferred to have semi weighted keys. I am also thing of the Keylab 61 or 61 mk2 and the Kontrol S61 mk2 if I go higher. I don't have experience with midi keyboards I only have with acoustic and digital. thanks for answering and any suggestion helps thanks
