HI! I have the Privia PX-130 and I am trying to connect my keyboard to my MacBook Pro running OSX 10.10.5 Yosemite. When I enter USB mode, a drive appears in my finder called "Piano" and holds three folders that include "MUSICLIB" "RECORDER" and "STATELOG". I want to use the program Synthesia with it, but the Synthesia program does not show my piano in the devices menu. I am unsure whether this is an issue with my Piano itself, my mac software, or the synthesia program and am seeking advice as to what steps I could take to find out which and solve the issue. Thank you!
