Was thinking this the other day. Having owned a few PSR's in my time as a youngster (PSR 500, 410, 520, 620 etc...) up until the PSR8000 before I jumped to Korgs I/Pa series. But when going back to Yamaha around the T3 era. Tyros started it's own line but the PSR's carried on, but as MOTL's?.. so were the Tyros' keyboards an upgrade from arguably the PSR9000Pro which was a TOTL PSR? If so, where does the PSR-S derive from, the PSR-740 line? So many PSR's that seemed to be both MOTL and TOTL's!! And the SX series now, if its not a mini Genos (which I think it is), then none of the PSR Sxxx were mini Tyros's either. Just trying to put some of this into context! Probably complicating everything lol

The 9000pro was not a psr series, and in my opinion, one of the best boards they ever made. I kinda miss mine every now and then.
The way I see it - The PSR-s line was a step downward, and the SX line is a new step up from the original PSR .... it sits just behind the Genos.

Hi Danny,
think where I might have gotten a bit confusing, there was the 9000 pro, (76 keys , no speakers) but there was also a psr 9000, ( 61 keys, with speakers)

Sounding a bit familiar?? Haha

Thank you guys.

Dave, you are right, the 9000Pro wasn't a PSR! Or at least I can't seem to see a PSR logo on the keyboard. It looks beautiful from the pictures I've seen of it. The only one of it's kind - until the T5's 76's keys version.

Rikki, yes it does sound familiar! I've never owned or even seen the 9000 series, but from all accounts the styles (and maybe even sounds) from the 9000 and Pro were quite different?

I think what I am trying to understand is where Yamaha broke away from the PSR series being TOTL. PSR seems quite misleading for the SX series I think as I think it's way better than a PSR model, especially when I think the SX900 is arguably more advanced than all the Tyros models.

The 9kPRO had solid, Tyros-like keys, harmonizer, hard drive, metal body, firm, quiet buttons .... IMHO - way ahead of it's time.

Upgrade should be your playing ability first and foremost..
At any rate is the upgrade KB it gonna make you play better then you do now?
The talent inside you is what matters not the keyboard.
what we have on the market today will be ancient in a few years..
just enjoy what you have for today....
if not dump it and get something else.

Hi Danny,
just in case you’ve never spotted this , might be interesting for you.

Yes the 9000 pro was a beautiful keyboard, really solid.
Sold mine to buy the kn7000.

Hi Rikki thank you for this, I will take a read. I've always been fascinated with progression and how these companies brought us to what we have today.

Yes, this was an interesting read. My 3000 is going on 16 years old now and still has more features than I come close to knowing how to use. I would probably be content with the 740 if I had the usb drive installed.
