After posting in here the other day, asking whether to go for a midi keyboard or a digital piano for piano practice and after thinking about it I’ve decided I want to go for the midi over a digital piano. I was originally looking at the novation impulse 61 key but seeing as people have recommended not using midi keyboards for actual piano practice I don’t know if this many keys are needed. Would be willing to spend up to like €300 but am more than happy to spend a lot less!! Thanks to you all in advance for the advice again
