Hi Dan,
MIDI files created on the S910 are in
XF format, but this "XF" VOICE STANDARD has nothing to do with the letters "XF" in the names of Yamaha Synths like Motif XF or MOXF.
In theory, such XF MIDI files can also played back on a
GM MIDI sound generator, but usually with reduced sound quality, i.e. "other" sounds.
Yamaha Synths are NOT XF compatible. If you play back an XF file on a Motif XF or a MOXF, to my knowledge, the internal
GM Voice Bank is automatically used (MSB=0, LSB=0).
If you want to use Voices of the
Preset or
User Voice Banks of a Motif XF / MOXF (MSB=63, LSB=0 ... 11) in a XF MIDI file, you have to
revoice the MIDI file with this new Voices (changing MSB, LSB, ProgramChange values). Please refer to the Voice Lists in the Data List of the Synth in question (and in the Data List of the S910 of course).
But note: XF MIDI files contain also many
Effect settings (Controller/SysEx). A Yamaha SYNTH will not be able to do anything with many of these XG Effect settings, so that you may have to completely reprogram the desired Effects on/for the Synth.
P.S.
Revoicing a MIDI file is to do relatively easy with the PC (Windows) program "Midifile Optimizer XI", developed by the German company "Midiland". The "Optimizer" supports e.g. Genos, SX900, S970, ...,
S910, and also the
Motif XF, but NOT the MOXF, MODX or the MONTAGE. (See also the attached picture.)
