XM and Dxx effect difference when saved/read in mpt vs. milkytracker

[mptlarm]

Hi, I've found a strange phenomenon.

If I save a .XM file in OpenMPT with a Dxx command = D0F, it is read as D15 in milkytracker, but when I open the file in OpenMPT it is read as D0F again.. How come? In milkytracker i can also save and load it as DFF but when read in OpenMPT it is read as DA5. If I save a XM with DFF in OpenMPT it only goes up to D5F when read back, and in milkytracker i get D95... weird!

Aah, sneaky. I've never used Dxx before and was a bit confused. Thanks.

... BTW, is there other commands that behave like this?

No, Dxx is the only command that is stored in a weird way in MOD/XM/S3M.
