I have tried to connect the px-s 1000 to a computer via usb midi playing a softsynth. When I send de output from the computer back into the aux line-in (not bluetooth) I also get a lag. I guess alltogether at about 7 ms. It is unfortunatly to much to use. The latency in the computer is about 3 ms but the latency in the aux input seems to be at about 4 ms too! Is there a way to avoid latency in the aux input?

It might be... At least very interesting that the noise only seem to come from one side of the key.

I seem to have much the same issue on my px-s1000. I have just had my keyboard for about a month , but been playing more than an hour a day. The black keys I use the most are starting to make a clicking sound. But I also noticed if you are pushing the black keys slightly from the right side, you can hear a click. From the left side, VID_20200627_144541.mp4 it is normally not possible to notice.
