It has no doubt many of the Fantom X sounds, including the grand piano and the acoustic guitar. If you are interested into hearing some official Fantom X demos, go here: www.roland.it
then click on "Fantom X series", followed by "Demo interattiva"; at this point you will find a page entirely written in english and -on the left side- you will have all the demo songs. A couple of them (Still solace and Akebono) sport the new grand piano; on Still solace you can hear also an acoustic guitar.
