I am still waiting for the PX-5S to arrive in the UK. But a library of song-based Stage Settings would be useful. This an area where, in my opinion, the Kurzweil PC3 and Yamaha Motif range excel. There are a huge number of song specific sounds already programmed or available for purchase as libraries. This saves a huge amount of time when preparing for corporate functions, weddings and to a lesser extent stage shows/musicals as a lot of the sounds required are already available. With regard to specific songs, This was started/covered in this thread: http://www.casiomusicforums.com/index.php?/topic/4239-song-ready-stage-settings/
