I owned one of these for three years and an excellent keyboard it was, with best ever keybed on line with the Rolands. A small disadvantage was lack of RAM which produced a lack of notes when used with an all on style accompaniment. Overall about the best Arranger board Yamaha have produced.

Didn't the 9000PRO drop the "psr" prefix? Mine didn't say PSR anywhere. Just thinkin' out loud....

The PSR-9000 Pro reminds me a lot of Roland's G70....still a good instrument in spite of it's flaws.

A friend of mine has two 9000 Pros...they both have the "PSR" prefix...both were later production models; maybe the earlier ones didn't have it...I can't remember if the early demo model I had was branded PSR....never really looked.

The 9000 Pro was a great concept that was poorly executed. Rather than expand on further software development to make the 9000 Pro what it should have been out of the box, Yamaha ditched the 9000 Pro altogether. Some of the "Pros" of the 9000 Pro were:

Great feeling 76 note keybed.
Extremely well built.
Lots of great sounds.
Expandability via Expansion cards.
Sampling capability.
Built in gooseneck lamp sockets.
Up to 256 note Polyphony with expansion cards installed.

Cons:

The CPU was extremely underpowered and couldn't handle all the tasks the 9000 Pro was capable of at the same time. That caused numerous problems such as timing issues, glitches, and lockups.

The Harmonizer was sub par compared to outboard processors. About the same as a Tyros II which is also sub par in my opinion.

Integration of expansion cards was an afterthought and it showed. This made full use of the expansion cards impossible.

Most real time controls were not integrated with the Expansion cards or synthesis features of the 9000 Pro. This could have been remedied in software updates but Yamaha decided not to support the 9000 Pro any longer.

The MTC timecode sync was atrocious. Caused mainly from the underpowered CPU being taxed.

Yamaha's customer support for the 9000 Pro sucked. Rather than admit the 9000 Pro had processor problems they tried to make me and many other 9000 Pro owners think it was an isolated issue. It wasn't, it couldn't be fixed, so bye bye 9000 Pro.

Yamaha had a great idea that was clearly underdeveloped probably due to some bean counter complaining about costs. When you are trying to build an all in one pro arranger don't cut corners. Yamaha should have taken a queue from Wersi and worked harder on the R&D. Pro's who are making serious money with their keyboards will gladly pay more for an all in one unit that truly works. Yes, your niche will be smaller at a higher price point but its better than making a turd that doesn't sell.

I remember Eric B. had one too. I got to play it at the San Jose jam hosted by Bebop. I thought it had a very nice sound and keyfeel.

Yep, I had one.
Great keyboard, UD is right, since it was geared for a different market(Pro), they dropped the psr.
Hence 9000Pro.

One of the reasons it was poorly executed was that it belonged to the Synth department rather than the arranger KB department(as far as I remember). They did not know much about arrangers and did not anticipate the end users needs very well.

I remember how much better the drums were on the Tyros....even the 3k for that matter. I loved that 9kpro, but the "goodies" were from an old mold.
It'd still be an awesome board for a live rig, or someone that just needed bread and butter drums and patterns.
