Ian cut the crap its terrible plain & simple unless your blind!! maybe no one want to speak up.....on top of that heres a few more BAD things with the S900....lettered access buttons on both sides of the keyboard A,B,C etc etc are very hard to see being they are the SAME Black color as the display bezel!!!!
USB ^ Mic inputs are in the worst place possible......when using an APEX KB stand they are totally blocked forcing you to pull the KB out a few inches....this is not fiction Ian PURE FACT....Yamaha design team really screwed up in these areas.......
sounding good is only one part of good keyboard.
