The SD-1 has a couple banks of ROM sound programs, as well as one RAM bank - and space for an (E)EPROM cartridge that can hold another one. Each bank holds 60 sound programs. Whatever you load from floppy will be loaded into RAM. But: there are files that hold a single sound program, or 30, or 60. Loading a 60-program file obviously replaces all RAM sound programs.
Either way, though, what I'd suggest is: find a diskette with some space free, and save the current contents to a new file - both the sounds and, if there are any, the songs and sequences. Incidentally, you can save a single file that holds the entire set of songs/sequences and sounds to a single file. This way you can load other sounds however much you want, because you can always reload the sounds you saved!

There are a lot of sounds built in in ROM; those will always stay there.

The OS disk contains the factory sounds; you can download the OS disk from the files section for this mailing list, and you can write a new floppy disk from that using the EDE program that you can also download from the files section.

It's not a difficult upgrade - you swap two EPROM chips for two replacement EPROM chips. In my view, it's probably worth upgrading to have the latest-and-best version.
