But all the new features get wrapped up in an arranger that sounds better than the previous one. So even if you don't use your arranger to the fullest, you buy a new one, you STILL sound better! Brilliant....!

As I said, thank God manufacturers don't build arrangers for the way most people use them. Your PSR3000 would never have come out, because, according to you, 90% of the users of the PREVIOUS PSR didn't use the features it had, and so on, ad infinitum. Why should Yamaha provide ANY advanced features that you use, if no-one else does? THAT'S the gist of your argument...? Might as well take the top and bottom 2 or 3 notes off of all pianos, given how seldom they are played!

Pros use the features they need AT THE TIME.... If the EQ isn't necessary to sound good, why learn it (it'll make you sound better, but better than what?)? If it IS necessary, they learn it..... Playing well is, of course, far more important than knowing every single esoteric feature, but trust me, most working pros know enough to make themselves a living. The truth of the matter is (and Fran's debacle on the MS just emphasizes this) having the most expensive arranger on your block doesn't make you a better player, and even knowing it's OS inside and out doesn't help THAT...... You've got to practice, practice, practice!

Most pros probably just learn enough of the OS to suit their professional need, and worry more about the important stuff..... you know - repertoire, playing skills, entertainment skills. Can't find out about any of that in the PSR Manual!
