APPENDIX
2) Bank-Select MSB adds an SFX bank
The Bank-Select LSB method is not useful for extension of distinctive SFX voices that
have no meaningful variation. For this reason the XG format supports a full SFX bank
of extension effects, which you can select by sending a Bank-Select MSB value of 40H.
Bank-Select MSB 7H, in contrast, can be used to set any channel to rhythm-part play.
Voice Modification: The XG format allows creation of extremely expressive control data
that can darken or lighten voices, delay or accelerate sound start-up, or implement many
other types of control. Most controls are issued by Control Change commands, although
System Exclusive messages are also used.
Effects: The XG format offers high-level effects support, enabling control of effects types,
circuit operation, and internal parameter settings for both basic and elaborate effects. De-
vices equipped with graphic equalizers will be able to modify ambience and sound to suit
the specific type of music being played.
External Input: Whereas existing tone generators create sound in response to internal data
only, the XG format provides for real-time participation by adding support for input of exter-
nal audio signals. External signals can be processed by the mixer in the same way as internal
tone-generator data. A model that supports this function would allow you, for example, to cre-
ate karaoke data that can automatically set the microphone echo used for playback.
