6. Voice selection *Non-GM1*

6-1. Voice Selection Procedure

The XG voice selection procedure is as follows.

• Melody voice Bank Select MSB = 00H,

use Bank Select LSB to specify the bank,

then use Program Change to select the voice

• SFX voice Bank Select MSB = 40H,

Bank Select LSB = 00H (fixed),

then use Program Change to select the voice

• SFX kit Bank Select MSB = 7EH,

Bank Select LSB = 00H (fixed),

then use Program Change to select the kit,

finally, use Note Number to select the voice

• Rhythm Kit Bank Select MSB = 7FH,

Bank Select LSB = 00H (fixed),

then use Program Change to select the kit,

finally, use Note Number to select the voice

For Kit and Voice mapping, refer to the “XG Voice List” and “XG Drum List” that are attached to

the XG Specifications. In the SFX kit, there are some notes within the valid range of notes that

produce no sound (that is, keys to which no voice is assigned).

6-2. Melody Voice Substitution

Tone generators that do not have the specified bank when a new melody voice is selected will

automatically substitute the sound of the previously selected bank. (By default, this will be the GM

basic sound set in Bank 0.)

As an example:

If you want Bank Select

MSB = 00H, LSB = 2DH, Program Change #29 Jazz Man

but a substitution of

MSB = 00H, LSB = 2BH, Program Change #29 Funk Gtr 2

is possible, first transmit

MSB = 00H, LSB = 2BH, Program Change #29

and then transmit

MSB = 00H, LSB = 2DH, Program Change #29

This slight detour will minimize the chances of an undesired replacement by the GM basic sound

set.
