Hello everyone I bought a Roland FP 30 earlier this week and I am encountering this strange sound when the black keys rebound. It is all the black keys, I am afraid because I am beginner and I am not sure if I am not suppose to let go of the keys that suddenly on a fast piece. https://streamable.com/080mw I asked on reddit and most people said it was a defect, what can you tell me about it.
