Not bad, see the datasheets Yamaha

UTILIZATION

So good is the Yamaha tweaked the software and the manual is not clear!

OVERALL OPINION

I am very happy with this machine to use as I did: complment of my guitars, piano et'appentissage. The sounds are good, especially the piano. But I ask him no more! The squenceur is twisted in death, the internal rglages the same.
In short, it is if we use a good target like mine!
