About Music Files
What are Music Files?
Music files contain musical information such as how long a
pitch is played, the force applied to the key or note played,
and other such information. Performance data is transmitted to
the MT-90U from music files saved in USB memory, and
played back as songs. This is different from an audio CD,
since the music file does not contain a recording of the sound
itself. This makes it possible to change the tempo and key
freely, allowing you to use the data in many different ways.
Regarding Copyright
Use of the internal songs and audio files for any purpose other
than private, personal enjoyment without the permission of the
copyright holder is prohibited by law. Additionally, this data
must not be copied or used in a secondary copyrighted work
without the permission of the copyright holder. Please be
aware that if you create derivative works that are based on
existing copyrighted material, such as commercially available
SMF music files, such works may violate copyright law if used
for any purpose other than personal enjoyment. Roland takes
no responsibility for any copyright violation you may commit
by creating such works.
VIMA TUNES
VIMA TUNES is a Roland specification for music files that
contain image and lyric data, allowing you to enjoy songs
with lyrics and images simultaneously. When data bearing the
“VIMA TUNES” logo is played back on a device that bears
the same logo, lyrics can be shown on the screen of a
connected external display or television, letting you enjoy
karaoke or watch a slide show.
* This unit (MT-90U) cannot play back VIMA TUNES images.
SMF Music Files
SMFs (Standard MIDI Files) use a standard music file format
that was formulated so that media containing music files could
be widely compatible, regardless of the manufacturer of the
listening device. An enormous variety of music is available,
whether it be for listening, practicing musical instruments, or
karaoke, etc.
SMF with Lyrics
“SMF with Lyrics” refers to a SMF (Standard MIDI File) that
contains lyrics. When Music Files carrying the “SMF with
Lyrics” logo are played back on the MT-90U, the lyrics will
appear in its display.
General MIDI
General MIDI is a set of recommendations which seeks to
provide a way to go beyond the limitations of proprietary
designs and standardize the MIDI capabilities of sound
generating devices. Sound generating devices and music files
that meet the General MIDI standard bear the General MIDI
logo. Music files bearing the General MIDI logo can be
played back using any General MIDI sound generating unit to
produce essentially the same musical performance.
General MIDI 2
The upwardly compatible General MIDI 2 recommendations
pick up where the original General MIDI left off, offering
enhanced expressive capabilities and even greater
compatibility. Issues that were not covered by the original
General MIDI recommendations, such as how sounds are to
be edited, and how effects should be handled, have now been
precisely defined. Moreover, the available sounds have been
expanded. General MIDI 2 compliant sound generators are
capable of reliably playing back music files that carry either
the General MIDI or General MIDI 2 logo. In some cases, the
conventional form of General MIDI, which does not include the
new enhancements, is referred to as “General MIDI 1” as a
way of distinguishing it from General MIDI 2.
GS Format
The GS Format is Roland’s set of specifications for
standardizing the performance of sound generating devices.
In addition to including support for everything defined by the
General MIDI, the highly compatible GS Format additionally
offers an expanded number of sounds, provides for the editing
of sounds, and spells out many details for a wide range of
extra features, including effects such as reverb and chorus.
Designed with the future in mind, the GS Format can readily
include new sounds and support new hardware features when
they arrive. Since it is upwardly compatible with General
MIDI, Roland’s GS Format is capable of reliably playing back
GM Scores equally as well as it plays back music files that
have been specifically created with the GS Format.
XGlite
XG is YAMAHA Corporation’s tone generator format. It
defines the ways in which voices are expanded or edited,
along with the structure and type of effects, in addition to the
General MIDI 1 specification. XGlite is a simplified version of
XG tone generation format. You can play back any XG music
files using an XGlite tone generator. However, keep in mind
that some music files may play back differently compared to
the original files, due to the reduced set of control parameters
and effects.
