[Dream] Yamaha FM editor for OS X??

[Mark]

I have a TX-7 (it's basically a DX-7 in a door stop).  I also have a
Macintosh running OS X and an AMT-8 MIDI interface.  So I'm looking
for patch editor/librarian software I can use to program the TX-7.
There is no way to program a TX-7 from its front panel.  Unlike a DX-7
it doesn't have buttons for that, and even if it did it would still
be tedious as all hell.  I know that Emapple more or less released a
half-assed version of Soundiver, but afaik, they haven't bothered to
finish it.  Nor do I feel like giving those asshats any more of my
money even if they did.  So does anyone know of an OS X editor for
Yamaha FM??  Freeware or shareware would be good.
