As far as I know the X5D features most (if not all) the ROM waveforms of the X5, 05R/W and N364. It's wave memory is *not expandable( so you cannot transfer samples (Although there was an odd type of RAM upgrade that allowed you to load AKAI samples. I cannot confirm that part though).
Since all these synths share the same synth engine the program/combi data should be compatible. At least judging by the specs.
