I have a Yamaha CX5M that still gets occasional use in my studio because of its FM synth module - but I'd like to make it more usable and use disk emulation rather than tapes! My plan would be to load the YRM-501 composer cartridge into the MEGA-RAM, and hope that it sees the mass storage as if it were a floppy drive. Do you think this would work? Thanks in advance!

It might work but is difficult to know for sure without trying the specific setup you suggest, so we cannot guarantee it will work. For sure you wont be able to use FAT16 partitions, but FAT12 (32MB max size partition).
Hi, thanks for the quick reply. But do I *need* MSXDOS2? The YRM-501 cartridge talks directly to the floppy, as I understand it (ie. it has it's own 'dos' as part of the functionality of the cart). So as long as the software sees the SD-512 as if it were a directly attached floppy, it should still work?
If I had a real floppy drive, I'd plug the fd-controller cart into the second cartridge slot in the back of the machine (if I had the rare-as-hen's-teeth CA-01 adaptor) and the music software cartridge in the top, and the software would talk to the floppy. So I could, for example, plug your FDC-600 into the back and attach a real floppy or my HxC, and do it that way. Problem is, I don't have a CA-01 (https://www.msx.org/wiki/Yamaha_CA-01), so I was wondering if the single SD-512 cart could do both things - be my YRM-501 cartridge and appear as a floppy drive to the software.
I know, complicated! Thanks in advance!
If the computer has only 32k ram and you are using the MegaRAM feature you wont be able to boot MSXDOS2. MSXDOS2 requires at least 128k, hence you need to have the RAM Mapper enable (which disables the MegaRAM).
