Hi Casio & Synth-Diy & AH -- sorry for the cross-posted followup.
Please direct replies to AH for now.

This is my email address.  I'll respond to the list as well because
others might find this stuff interesting.

There is only one Rev 4 software at present.  People have talked a lot
about redoing the OS, but I think future plans will involve replacing
the CPU board as well.

Yes.

With a hardware modification, yes.

I posted this information a while back to AH.  See:

There should be no problem with patch dumps.  Rev4 modified global
MIDI capabilities but did not affect the voice architecture at all.  I
would take the precaution of saving the patch data to a WAV file or
similar, normalize the audio output, then load into the other unit.

Not that I know of, sadly.  I've asked around, too.  I also don't have
the original test tape, but I can re-create it with a bit of work as
required.

Cheers,
Joan
