UTILIZATION

No particular concern for the config. I just had a problem of driver for my pc cnnection but after a ride on the Yamaha website, more problems.
for the rest, but happiness, just select the sound and go!

OVERALL OPINION

6 months I use it and no particular problem except with the usb.
I like the intuitive side of the keyboard: no programming, just select the sound and go!
plus the two knobs can really change their sound and it can go even further.
the value seems good. Of course there are much better but more expensive too.
