I am looking to upgrade my keyboard from one with unweighted (springy) keys to one with weighted keys that feels more like a real piano.
I'd like to buy the new CASIO PX-S1100. When I look at a lot of reviews of the keyboard there seems to be some contention over the black keys being lighter than the white keys. When I played the PX-S1000 in the store I could not tell the difference between the white and black keys but that is probably because I am a beginner and the difference may become more noticible as I get more experienced.
I am looking for some clarity on piano key weighting.
What causes the "weight" of a key in a real piano?
Is there a weight range that piano manufacturers aim to be in with their key weighting?
I understand that keys get lighter as you move to the higher keys. Why is that? Is that consistent across every piano?
Wouldn't every piano manufacturer aim to have the black keys lighter because the length of the key is shorter so it is a shorter lever that might "feel" heavier?
If I spend a lot of time practicing with the PX-S1100, when I play on a real piano will having equally weighted keys feel weird?
EDIT - Here are some of the reviews from different perspectives that I have watched regarding the PX-S1100:
Merriam Music mentions the weighting issue at 10 minutes & talks about it for the rest of the video.
Pretty much the entire ThePianoforever video is about the key weighting issue.
PianoManChuck didn't consider key weights important enough to mention is his video at all.
