Yamaha's do have very sscolid OS's, that's for sure. I think that in the 1500 performances that I did with the S900, I only had to turn the keyboard off and on three times.
If you recall, the S900 had some quality control issues, and dozens of them had to be exchanged. I had two screwed up ones. Of the two replacements, one needed a new screen after 20 months. This cost me $125. One of the a/c adapters needed repair which cost me $20.
I completely resonate with the frustrations people have with the vocalizer, which is sometimes serviceable. The S910 has a couple of new parameters on the vocalizer to adjust it to the singer's vocal range.
I wish the S900/910 had a dedicated TALK button. I do a little bit of humorous patter with my show, and it's annoying having to press two buttons to turn TALK on and off. Sometimes I forget to turn it off, and I play half the song with a lower volume and no reverb.
I think the drums have improved in the last ten years, but Yamaha is probably behind the others for a really live feel. The drums sound somewhat processed. I have never had a complaint at a live gig, but I have heard comments - not among arranger players - that the recordings that I have made of my own songs could benefit from a more live drum feel.
I am surprised that of the T3 expansion packs that Yamaha came out with, that none included a drum pack, even though it makes sense because I believe that in the T3's OS just like with the PSRs, you can't use a USER voice in a style.
I think the Yamaha's have a great layout with few glitches. I have never thought that I had the perfect keyboard. But I do think I have a fantastic keyboard.
One thing that I think Yamaha should do is make it so that if a voice/style/multipad file is missing from a registration, instead of loading the registration without it, instead, like Windows, the keyboard should give a message that it can't find that file and to ask if you want to locate it or cancel. Just think, if I want to change the name of a folder that my styles are in, none of my registrations will find that style.
Another great thing about the PSR line is how light the keyboard is.
Whenever the seniors I perform for ask how much the keyboard cost, I tell them the retail value - $1700 or $1750, and these folks who lived through times when a candybar cost 3 cents, are shocked that a board that sounds like a symphony orchestra can be so cheap. I have to agree.
