I have a d824 and am looking for a portable fostex recorder for tracking, to then transfer and mix 8 tracks on the 824. Anyone have experience transfering between fmds3 or fdio1 with diferent versions? The 824 uses version fmds3 version 2, but older units use version 1. Is there a diference for this purpose?

If this has been discussed please share the link.
I would ask fostex but dont know where.
