Gary, I'm not agree with you.
There are a lot of keyboards that shows entirely timing.
I encountered a problem, for example, on my ex-Tyros 5, when I load a mp3 file does not show me the entire time of mp3 (total time), but only elapsed time. Elapsed time of what?!
So, for a long time I have to pleased my friend and colleague from my band to use mp3's on his PA3X, which shows "<time elapsed> from <total time>" near mp3 title.
Yamaha has a lot of "not understanding" shortages/minuses. I don't understand Yamaha's programmers! I Really don't understand!
