Music Files That the KR Can Use
What Are Music Files?
Music Files contain information describing the details of a
musical performance, such as “the C3 key on a keyboard was
pressed for this amount of time, using this amount of force.”
By inserting the floppy disk into the disk drive on the KR, the
performance information is sent from the floppy disk to the
piano, and played faithfully by the piano. This is different
than a CD, since the music file does not contain a recording
of the sound itself. This makes it possible to erase certain
parts, or to change instruments, tempos and keys freely,
allowing you to use it in many different ways.
Regarding Copyright
Use of the song data supplied with the Data Disk attached to
this product 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, nor used in a secondary copyrighted work without
the permission of the copyright holder.
■ The KR allows you to use the
following music files
● Floppy disks saved on a Roland MT Series, or Roland Piano
Digital HP-G/R and KR Series instrument
● Roland Digital Piano Compatible Music Files
Roland’s original music file is made specifically for practicing the
piano. Some follow an instructional curriculum, allowing for a
complete range of lessons, such as “practicing each hand
separately” or “listening to only the accompaniment.”
● SMF Music Files (720KB/1.44MB format)
SMFs (Standard MIDI Files) use a standard format for music file
that was formulated so that files containing music file could be
widely compatible, regardless of the manufacturer of the
listening device. An enormous variety of music is available,
whether it be for listening, for practicing musical instruments, for
Karaoke, etc.
* If you wish to purchase SMF Music Files, please consult the
retailer where you purchased your KR.
SMF with Lyrics
“SMF with Lyrics” refers to SMF (Standard MIDI File) that
contains the lyrics. When Music Files carrying the “SMF with
Lyrics” logo are played back on a compatible device (one
bearing the same logo), the lyrics will appear in its display.
■ About the KR Sound Generator
The KR come equipped with GM 2/GS sound generators.
General MIDI
The 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 meets the General
MIDI standard bears 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 the General
MIDI, Roland’s GS Format is capable of reliably playing back GM
Scores equally as well as it performs GS music files (music files that
have been created with the GS Format in mind). This product
supports both the General MIDI 2 and the GS Format, and can be
used to play back music data carrying either of these logos.
XG lite
XG is a tone generator format of YAMAHA Corporation, that
defines the ways in which voices are expanded or edited and 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.
