Fantom-Xa includes 64 Mb wave ROM that is identical to that of the Fantom-S series. Polyphony is 128 voices, and up to 512 Mb DIMMs may be installed - like on the X series. It includes all Fantom-S patches, as well as 128 all-new patches and some new rhythm kits.
The more exciting thing is that I have been involved in demo composition for this new Fantom-Xa, and you will also find preset samples on this one created by me. Soon the demo (named Auto Mate) will be available on Roland's sites, and more info on my work will be published at Artemio.net.
