Chapter 10. Using the XP-80 as the GM sound source

The XP-80 features a GM mode – a convenient way to play
back or create GM score data (music data for GM sound
sources). You're able to play back commercial GM score data
releases and even modify various parameter settings for
enhanced musical expression.

Entering GM mode

Use GM mode to place the XP-80's sound source in GM
System compatible mode. Basically GM mode is similar to a
special kind of Performance in which a GM System Rhythm
Set is assigned to Part 10, and GM System Patches are
assigned to other Parts. But however, you can't store GM
mode settings in user memory.
The Play display (GM) shows a Patch or Rhythm Set
assigned to each Part. Each time you enter GM mode, the
GM Drum Set is assigned to Part 10, and Piano 1 is assigned
to other Parts. You can also select other GM Patches and GM
Drum Sets for each Part to match the performance.
<Procedure>
Hold down [SHIFT] and press [PERFORM] to call up
the Play display (GM).
When you switch the XP-80 into GM mode, the sound
source initializes itself for basic GM System settings.
To change the current Part, press [l] or [r].
To change the GM Patch or GM Rhythm Set assigned
to the Part, perform the same procedure as you do
when you select a Patch or Rhythm Set.
Initializing the sound source for GM
System basic settings
To play back a GM score correctly, the sound source must
first be initialized to basic GM system settings. The XP-80's
sound source is initialized in the following situations:
When the XP-80 is switched to GM mode
When it receives a GM System On message from an external
MIDI device
When a GM System On message is encountered in the song
data being played back
At power on
When you execute the GM Initialize function (p.176).
Because effects settings are not defined in the GM
System, they will not initialize to factory settings
unless the GM Initialize (DEFAULT) or Factory Preset
is executed.

<GM System On message>
The GM System On message puts the unit in a state that con-
forms to the GM System and initializes a GM-compatible
sound source.
If the Rx GM-ON Message parameter (SYSTEM/MIDI
Param2) is set OFF, GM System On messages cannot
be received.

Playing back a GM score

When the XP-80 is in GM mode, it plays back GM scores cor-
rectly. But beyond this, the XP-80 provides many extended
features not defined in GM System specifications, and if you
create music data using these extended features, your song
may not play back correctly on other GM-compatible sound
sources.
The XP-80 is not compatible with the GS format (stan-
dard format for multitimbral sound sources advocated
by Roland). Music data bearing the GS logo (GS music
data) may therefore not play back correctly on the XP-
80.
<Procedure>
Hold down [SHIFT] and press [PERFORM] to switch
the XP-80 into GM mode.
The beginning of a GM score normally contains a GM
System On message. So if you play back a GM score start-
ing in the top of a song, XP-80 will switch itself to GM
mode. But if you play back a GM score starting in the
middle of a song, XP-80 may not switch itself to GM
mode, and the GM score may not play back correctly. So
to be safe, it's recommended to manually set the XP-80 to
GM mode before playing back a GM score.
Press [SEQUENCER] to call up the play display(SEQ(Song)).
Move the cursor to the song number and select the
number of the song you wish to play back.
Press [STOP/PLAY] to begin play back.
When the song ends, playback will stop automatically. To
interrupt play back, press [STOP/PLAY].
The procedure for playing back a GM score is the same
as for playing back a regular song. If you wish to mod-
ify the playback tempo or to playback the song repeat-
edly, refer to "Playing back a song" (p.97). Recording
and editing a GM score is also the same way as for a
regular song (p.104–, 117–).
Muting a specific Part
When you switch over to GM mode, all Parts will be set to
receive MIDI messages. To turn off a specific Part so that it will
not sound, set the Rx Switch parameter to OFF for the Part.
<Procedure>
Press [LOCAL/TX/RX] to open the LOCAL/TX/RX
window.
Press TRACK/PART [1]–[16] to switch each Rx Switch
parameter for the Part ON (indicator lit) or OFF (indi-
cator off).
The Parts set ON are indicated with "o," and those set OFF
are indicated with "-."
