MIDI Data Compatibility
This section covers basic information on data
compatibility: whether or not other MIDI devices can
playback the data recorded by PSR-2100/1100, and
whether or not the PSR-2100/1100 can playback
commercially available song data or song data created for
other instruments or on a computer. Depending on the
MIDI device or data characteristics, you may be able to
play back the data without any problem, or you may have
to perform some special operations before the data can be
played back. If you run into problems playing back data,
please refer to the information below.
Disk format
Floppy disks are the main storage medium for data used
with various devices, including computers. Different
devices have different systems of storing data, therefore it
is necessary to first configure the floppy disk to the system
of the device being used.This operation is called
“formatting.”
•There are two types of floppy disks: MF2DD (double
sided, double density) and MF2HD (double sided,
high density), and each type has different formatting
systems.
• PSR-2100/1100 can record and playback with both
types of floppy disks.
• When formatted by the PSR-2100/1100, a 2DD disk
stores up to 720 KB (kilobytes) and a 2HD disk stores
up to1.44 MB (megabytes). (The figures “720 KB” and
“1.44MB” indicate the data memory capacity. They are
also used to indicate the format type of disk.)
• Playback is only possible when the MIDI device to be
used is compatible with the format of the disk.
Sequence Format
The system which records song data is called “sequence
format.”
Playback is only possible when the sequence format of
the disk matches that of the MIDI device. The PSR-2100/
1100 is compatible with the following formats.

■SMF (Standard MIDI File)

This is the most common sequence format.
Standard MIDI Files are generally available as one of two
types: Format 0 or Format 1. Many MIDI devices are
compatible with Format 0, and most commercially
available software is recorded as Format 0.
•The PSR-2100/1100 is compatible with both Format 0
and Format 1.
• Song data recorded on the PSR-2100/1100 is
automatically recorded as SMF Format 0.
• Song data loaded to the PSR-2100/1100 is
automatically saved as SMF Format 0 regardless of the
original format.

■ESEQ

This sequence format is compatible with many of
Yamaha’s MIDI devices, including the PSR-2100/1100
series instruments.This is a common format used with
various Yamaha software.

■XF

The Yamaha XF format enhances the SMF (Standard MIDI
File) format with greater functionality and open-ended
expandability for the future.
•The PSR-2100/1100 is capable of displaying lyrics
when an XF file containing lyric data is played.

■Style File

The Style File Format – SFF – is Yamaha’s original style file
format which uses a unique conversion system to provide
high-quality automatic accompaniment based on a wide
range of chord types.
