Hello! I just got my PX 560 today and I'm in love! One thing I noticed, though. Say I assign knob 1 to affect attack time of upper 2 but not upper 1 (for example to affect the aggression level of the strings without affecting the piano). In this configuration, the attack time value displayed on the main screen doesn't appear to change as I turn the knob. The string attack does in fact change, it's just not represented visually which makes it a little hard to know what you're doing at a glance. Is this intentional, or a bug? Anyway, just a little nitpick. This thing is fantastic!
