Feature:
Very fine set of features. The styles are quite good and very useful in song writing. The controls are useful and well engineered. I was considering several non-arranger keyboards but decided on this instead. I am glad I did. An arranger provides many more featuers to assist in composing songs. The microphone / vocal features are what put this over the top for me.

Quality:
The quality is typical of Yamaha - very high. The one thing I wish it has is a mineral crystal screen instead of plastic.

Value:
Good - expensive buy worht it for what it does.

Desirability:
It has what I want in one package.

Sound:
Excellent sounds for a keyboard. I use a pair of Yamaha owered monitor speakers to provide a greater sound quality than built in speakers can deliver.

Ease of Use:
Very well done. Easy to use. Easy to learn. Nice job Yamaha. There are multi level menues for advanced features if one needs them. Basic features are easily accessible and well set up.

Support:
I sent 3 emails to support center and never received a reply. I finally called support and received an answer.

Overall:
The best arranger for my needs.

Feature:
The featuers are also very very good except for 1 thing. If it only could have a built in sampler with sampling capabilities like the prs 8000\9000 and tyros.

Quality:
Sound quality, S. ariculation voices + the coloured LCD makes it good

Desirability:
its just too good for it's price its smaller brother psr s700 dont have the chance to beat this guy

Sound:
sounds great high quality samples from the tyros and super articulation voices are too good to be true.....

Ease of Use:
style playing etc is not veryhard. well at least i could use it as i wanted. it have lots of complicated functions and very good for programming voices. if i own it well i'll rate it 10. for first time users it's just too complex

Overall:
I want IT......
