I don't think that is correct.
FAT16, when using standard 8.3 short filenames, has a maximum of 512 root directory entries.
Once you add long filenames, plus the short 8.3 alias (if used by the OS), that can be reduced dramatically.
Considering that Akai seems to have specifically made OS 1.20 in order to format MCD cards with a directly Windows PC compatible file system, I think that it is possible that the FAT16 structure has been setup with space set aside in the root directory to handle maximum length Windows long filenames as default...
http://en.wikipedia.org/wiki/Long_filenameThe long filename system allows a maximum length of 255 UTF-16 characters.

This is achieved by chaining up to 20 directory entries of 13 2-byte unicode characters each.

Limitations
Because the FAT LFN implementation is layered on top of an older, more limited naming system, there are inevitable complications, such as if an attempt is made to create too many files with the same first six letters. In addition, one is more likely to encounter issues creating files or folders in the root directory, since FAT16 only allocates space for 512 root directory entries. Since long filenames can use more than one directory entry, this problem may occur with fewer than 512 files or folders in the root directory. In fact there is space only for 25 long filenames of maximum length (512/20).
So, that Wiki article claims that on FAT16 there is only space for 25 root directory entries, if using full length Windows 255 character long file names, and Jimmy says...

Shouldn't be very hard to test it.
