I purchased a small Yamie Psr 290, for my music school and I had a nice surprise.
Voices and styles are great and the Yes(Yamaha Education Suite) works very well.
I can transfer the music lessons (over 30) from the computer via song filer software and store in the small 290 ram.So, the students can play the right hand (290 makes the acc)or the acc.(290 makes the melody) or play both hands with the mid play back(290 makes the evaluation of the performance).
Another tip: I loved the DJ function with a lot of Dj voices.I sampled all voices to my 9000pro and made some OTS with dance and disco styles.
I am sure that 290 is a great choice(here in Brasil US$280)as first kbd, and the most
"bang for the buck" as small kbd.
