APPENDIX
Master Tune can be modified either with System Exclusive messages or on the front panel of
a tone generator. Two System Exclusive messages are available i.e. MIDI Master Tuning (F0,
43, 1n, 27, 30, 00, 00, mm, ll, cc, F7) and XG Parameter Change Master Tune (F0, 43, 1n,
4C, 00, 00, 00, dd, dd, dd, dd, F7).
If the parameter is modified with F0, 43, 1n, 4C, 00, 00, 00, ... and then the XG System On
comes, it will be reset to the value which has previously been modified with F0, 43, 1n, 27,
... or on the front panel e.g. :
Master Tune value
On the other hand, the value set with F0, 43, 1n, 27, ... or on the front panel would not be
reset to any earlier one with a reception of XG System On :
Master Tune value
With regard to the relation between the modification with F0, 43, 1n, 27, ... and the one on
the front panel, the last executed one will take the priority.
The message requires approximately 50msec to execute, so sufficient time should be allowed
before the next message is sent.

Initializes all the parameters to the XG default settings, with the exception of Master Tune
value.
As for the Master Tune, reception of this message should be implemented in the same way as
the case with XG System On.
