When playing the CFX piano I notice some of the keys do not "ring" or sustain when I hit the key and hold down the sustain pedal. I start to notice this with the 2nd E note above middle C. Not every key in that upper register does this, but probably the most noticeable key is the 2nd G# above middle C. The keys that don't exhibit the problem have a nice sustain, but the problem keys do not. I did just do the latest 1.3 update, so not sure if this had anything to do with it. It really bugs me, especially since the CFX is the piano I most often use.
