Some of this is relevant to backward and forward compatibility's *within*
Yoshimi versions. For example, I run three machines and they don't all have the
same version. My 'music' machine always has a slightly older version -
stability matters there!
Although we try to retain compatibility with older versions of both Yoshimi and
Zyn, there's a practical limit to what we can do, but we should be able to
maintain full forward compatibility.
Files stored in the clipboard could have a different extension (or even none),
but why make that a different (extra) bit of coding?
