Music Files That the KF-90 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
KF-90, 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

■ The KF-90 allows you to use
the following music files
● Floppy disks saved on a Roland MT Series, or Roland
Piano Digital HP-G/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 KF-90.
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 KF-90 Sound
Generator
The KF-90 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.
