Yamaha Electone EL-900 Owner's Manual page 166

NOTE:
The M.D.R. section of the EL-900 allows
you to play back the commercially
available XG song data and convert the
data created by the EL-900 to the XG
compatible data. See page 101 for more
information.
NOTE:
When you create an XG song data using a
sequencing software, be sure to insert the
XG System On message at the beginning
of the data. The internal tone generator
mode automatically changes to XG when
you start to play back the data.
NOTE:
The internal tone generator mode
automatically changes to XG when you
play back commercially available XG song
data.

Use the EL-900 as an XG Tone Generator
You can also use the EL-900 as an XG tone generator since the EL-900 is
compatible with the XG format. You can play back the commercially available
XG song data with the electoneﾕs M.D.R., and also play them using an external
sequencer (or sequencing software) and the internal XG tone generator.
The internal tone generator section of the EL-900 is normally set to EL Mode
for playing as an ﾒElectone.ﾓ
Sending an appropriate system exclusive message from the sequencing software
(PC) to the EL-900 changes the mode to XG Mode, in which you can use the
Electone as an XG tone generator.

Once the XG System On message is received, the internal tone
generator will be in the XG Mode allowing the EL-900 to all the MIDI
messages defined by the XG format such as NRPN and Bank Select.
