There are indeed X5D banks for the presets of the M1, the 01/w, and the N364 available on the WWW. This possible because of the common
AI/AI2 synthesis engines and the similarities of the PCM sample sets. This beeing the case, the X5D still cannot be directly loaded with 01/w sysex files. However, there is an application called PatchMagic that does translate sysex files for the M1 and 01/w into X5-compatible sysex files. A company link is available in the Korg Zone page on this site, I believe. It costs about $50US and it would allow you to develop sound banks on your workstation and the convert them for use on an X5 or X5D.

Hope this helps.
