All the sounds are very authentic and useable. Noteworthy are the outstanding piano and organ presets.

The controls are sensibly placed and easy to manipulate.

It's a Yamaha!

Since I was able to trade in a Yamaha P80 Piano, Korg Karma Synthesizer and a Korg CX-3 Organ towards one keyboard that beats all three, I'd say it was an excellent value.

I haven't had any need to contact Customer Support. The Owner's Manual is very thorough and Yamaha's Internet User's Group Website is outstanding.

I wanted the sounds and I wanted the incredibly responsive keyboard. Like the man says, "It has everything I want and nothing I don't want".

This piano is far from entry level, not as hardcore as a Motif workstation but it packs the same spirit, & has a great value for only 1,300 dollars. Excellent action as well as very well timed velocity and feedback response.

Excellent amount of features, I found that this piano is not only loaded with its own built in sounds, but you can plug a USB cable into your laptop and use it as a MIDI controller. Though you may not want to considering the built in sounds are very suitable for any on stage or studio need. *I use an M-Audio Prokeys currently, I plug that into my laptop and use the MIDI features in Apple's Logic Pro. Im satisfied with the sound.. but horrified at the terrible action and velocity response of the keyboard. This Piano took only minutes to commit me into a buy, and 95 minutes later I was ready to hand over my debit card.

"plug and play" a little hunting around to find the transmition features for use of the USB interface overall not bad.

Close your eyes, sit back, & it feels like your sitting at a baby grand.

High quality construction, I would like to believe thats real wood on the side.. but its only laminated. None-the less the keyboard is very very well built.

I just played it in the store for about an hour.

If your still using a semi-weighted midi controller, or your neighbors casio keyboard this piano makes a wonderfull addition to any musicians collection, as well as being able to show of a professional grade instrument.

Yamaha has done a tremendous job with this instrument. They created this instrument for the everyday performer. Out of the box, it is easy and intuitive--requiring only a quick glance through the manual to understand the user interface. This unit is extraordinarily versatile and expressive. The quality of the piano sound is particularly noteworthy. The overall soundset is so diverse and expansive that it will take days just to audition all that this unit has to offer. Overall, the quality of sounds and the feel of the weighted keys is exemplary. None of the competition even comes close when compared side by side.

A true performance instrument...everything included to get started and then some. Interfacing with my p.c. is a snap...thanks to the included software.

A paragon of Japanese engineering...Well-made and reliable so far.....Brand new with factory support eliminates potential hassles and worries. Appropriate for myriad musical styles...few limitations. If my DX7 is any indication of this unit's longevity, the S90 will be around for a long time.

Great value! Tremendous bang for the buck!

No problems to report whatsoever.

Great sex appeal...in a Japanese sort of way. Excellent, logical design...a paragon of engineering...It has supplanted all the other gear in my studio.

This is a great sounding keyboard. Overall, I love it. One minor complaint. The multisampled piano is clean and light -- great at low and middle volumes, but they don't seem to have sampled really hard attacks. It just doesn't thunder quite like a real piano, or even like the better Gigastudio pianos. It also doesn't model damper noise or pedal-down resonance. So,in the studio, I'm sticking to real piano, or at least one of the "big" sampled pianos (with the S90 as controller). But I'd still be happy to play the S90 live vs. most of the pianos out there in the world.

Way more features than I'm ever gonna use.

Like all Yamaha stuff, the S90 is designed to last, and is very solid. This one lives in my studio, but I wouldn't hesitate to take it on the road. (It is a big, heavy keyboard though - no fun to carry.)

Pricing is right in line with comparable keyboards.

The only problem I've ever had with any Yamaha equipment is that the floppy drive belt on my SY77 broke after about 10 years of use. I fixed it myself and continued on my way. Yamaha is good about updating drivers and software via their website, and there's a big group of users and 3rd party sound designers out there on the web.

By far the best 88-key weighted action around. Light, fast, very similar to Yamaha's piano action in feel. In fact, I bought it mostly for the action, as a controller, after trying every weighted keyboard I could get my hands on.
