SY-99 microtuning-- possible to save to disk?

Does anyone here know if the Yamaha SY-99 can save microscales to disk? or does it
just have the 2 on-board memory programmable scales? The DX7 II-FD has a RAM
cartridge that can supposedly hold up to 63 tunings, but on microtonal-
synthesis.com they don't say what the SY-99 can do if anything. Anybody know
anything about this? The people on the Yamaha groups don't do much microtuning
and don't know... -Justin

The SY99 can save all data (including the two user-programmable
microtunings) to disk, but you have to load that data back into the
machine to access it, so you're still limited to two custom tunings at
one time. However the SY99 also has a slot for a RAM data card that
will allow you two additional custom tunings. The only constraint is
that user-defined ("internal memory") voices can't use card tunings
and card voices can't use internal memory tunings Unfortunately it's
nearly impossible to get your hands on one of those data cards, I'd
like to have one myself.
