I would never critique a keyboard from a video of such poor quality.
Below is a different YouTube video link and its most likely recorded directly from line outs of the board or perhaps through a mixer, but definitely not from a phones recording of the sound emanating through some speaker.
Not a bad piano sound at all in my opinion.
Disappointed this person didn't post examples of styles etc. only the piano and vocal.
Let's wait for more of these higher quality recordings before passing judgement.
Enjoy


I'm looking forward to getting my own hands and ears on this board. I'm thinking it going to be a LOT of bang for the buck. Very surprised though that it is not a 76 key like the previous older WK 3000/3200 series etc.
