MIDI tuning files for Yamaha S90es?

Has anyone tried sending a MIDI tuning file to a Yamaha SW90es.

I have been successful in controlling this synth with Scala (see

http://www.sninety.com/forums/showflat.php?Cat=1,3&Board=S90ES&Number=359021&page=0&view=collapsed&sb=5&o=&fpart=1)

But I would now like to try downloading a MIDI tuning file into the
S90es' synth tables.

My hope this will allow me to play simultaneous notes--whereas when
controlled by Scala, I believe all keyboard notes are "bent" when an
alternately tuned note is sent to the synth.

I'm new to the technical aspect of alternate tunings though in my
early days (60s) I played in Turkish, Persian, and N. African
performance groups that required playing using alternate tunings (we
referred to this as quarter tone flat or sharp notes in a mode). You
had to have an ear for these tunings or you were out :-)

Thanks,

Len

Judging from the SW90's manual it's not possible. It contains two
dozen preset tunings, but no user tuning table. Too bad!
