Chapter 9 Examples of Applications Using the XV-3080
Chapter 9
Using the XV-3080 as a
General MIDI Sound Module
The XV-3080 features a GM mode—a convenient way to play
back or create GM score data (music files for General MIDI
sound module). You’re able to play back commercial GM
score data releases and even modify various parameter
settings for enhanced musical expression.
Entering GM Mode
Basically GM mode is similar to a special kind of
Performance in which a General MIDI System Rhythm Set is
assigned to Part 10, and General MIDI System Patches are
assigned to other Parts.
But however, you can’t store GM mode settings in user
memory.
fig.9-02
The GM PLAY page 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.
1. Press [GM] in MODE to call up the GM PLAY page.
When you switch the XV-3080 into GM mode, the sound
generator initializes itself for basic GM System settings.
2. To change the current Part, press [ ] or [ ].
3. 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 Generator for
General MIDI System Basic Settings
To play back a GM score correctly, the sound generator must
first be initialized to basic GM system settings. The XV-3080’s
sound generator is initialized in the following situations:
• When the XV-3080 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
• When the XV-3080’s power is turned on.
• When you execute the GM Initialize function (p. 145).
Playing Back a GM Score
When the XV-3080 is in GM mode, it plays back GM scores
correctly. But beyond this, the XV-3080 provides many
extended features not defined in GM System specifications,
and if you create music files using these extended features,
your song may not play back correctly on other GM-
compatible sound modules.
In addition, although the XV-3080 can also be compatible
with the GS format by receiving a GS Reset MIDI message,
Roland’s Sound Canvas Series (including the SC-8850 and
SC-8820) features a different sound module system and
extended tone map, you may be unable to get MIDI data (GS
music data) created especially for use only with the Sound
Canvas series of devices to play back properly.
The beginning of a GM score normally contains a GM System
On message. So if you play back a GM score starting in the
top of a song, XV-3080 will switch itself to GM mode. But if
you play back a GM score starting in the middle of a song,
XV-3080 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 XV-3080 to GM mode
before playing back a GM score.
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 Receive Switch to OFF for the Part.
First, press [RX] to make its indicator light.
At this time, the on/off setting of each Part will be shown by
the indicators of PART SELECT [1/9]–[8–16]. When the [1-8/
9-16] indicator is dark, the function button indicators will
indicate the status of Parts 1–8. When the [1-8/9-16] indicator
is lit, the function button indicators will indicate the status of
Parts 9–16. Lit is on, and dark is off.
Press PART SELECT [1/9]–[8/16] to turn the Part on/off.
