Ah, you're assuming that the SynthDef name comes from the filename.
That's not true.

The SynthDef name is part of the binary contents of the file. You
copied to a different filename, without changing the contents of the
file, so the SynthDef name *inside the file* is still named fmgen_a_0.
The filename is 100% irrelevant.

Consider that the normal case for transmitting a SynthDef to the
server is in an OSC message: `add` constructs a `/d_recv` message. In
this case -- the normal case! -- there is no filename, so it doesn't
make sense to assume that the filename provides the defname.

Also note that a scsyndef file can contain multiple SynthDefs --
usually it doesn't, but it is possible to create a package of several
SynthDefs in one file. Every SynthDef needs to have a unique name --
so, as there is only one filename, it would be impossible to infer
multiple defnames from it.
