I'm not sure. The X5D has more samples than the X5. The X5 may play all of these other synths but I don't know for sure. Just go to synthzone homepage...go to Korg...and there are a few sites that have x5 and x5d zip files for all of those korg synths...Korgy Park is another good place to go. I like X5 Banks because it is pretty basic. Just go there and you will see what I mean. If you would, please respond about what you think about the site...I have nothing to do with any of them.
