Greetings, I see that folks are still responding to my original post, and I appreciate it! I actually returned my PX-5S over a year ago, as I found my particular unit unplayable (I opted to buy a keyboard from a different manufacturer). As described earlier, the black keys required greater pressure to produce the same velocity levels. To test this, I recorded a bunch of music, then checked the MIDI files for velocity levels of each key. The black keys uniformly registered about 10% lower. This difference was readily audible. I asked a friend to sample the keyboard, and she picked up on this issue right away. Again, not sure if it was just a bad unit or a model-wide problem, but it sounds like "flaviogmaia" is experiencing the same issue.

Thanks for your responses. I recorded a variety of MIDI tracks, and then spent time looking at the velocity levels (acoustic piano sample only). The note in question (G above middle C) did in fact register about 10% higher than nearby white keys. Of greater concern, though, is that the black keys (pretty much all of them) register considerably lower than the white keys. In other words, in order to create the same volume level, greater pressure is needed on the black keys vs the white keys. As a result, playing this keyboard feels very unnatural to me, especially in comparison to my acoustic piano (an unfair comparison, perhaps). Again, thanks for your help. My search for the perfect digital piano continues...

I just received my PX-5S a few days ago and have spent considerable time playing it. I noticed something right away with the acoustic piano samples: one key-- the G above middle C-- sounds louder than the others. The same touch/pressure seems to trigger a higher velocity layer on this key. Naturally, this is quite distracting (I find myself overcompensating by trying to play this key with a lighter touch). I am wondering if this is a problem with my particular unit, or if other users have experienced something similar. If anyone out there could do a quick check, I would greatly appreciate it!! (play some runs that include this note, see if it sticks out like a sore thumb). Thanks for your help.
