The system which records song data is called "sequence
Playback is only possible when the sequence format of
the disk matches that of the MIDI device. The PSR-2000/
1000 is compatible with the following formats.
I 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-2000/1000 is compatible with both Format 0
and Format 1.
• Song data recorded on the PSR-2000/1000 is
automatically recorded as SMF Format 0.
• Song data loaded to the PSR-2000/1000 is
automatically saved as SMF Format 0 regardless of the
This sequence format is compatible with many of
Yamaha's MIDI devices, including the PSR-2000/1000
series instruments.This is a common format used with
various Yamaha software.
The Yamaha XF format enhances the SMF (Standard MIDI
File) format with greater functionality and open-ended
expandability for the future.
• The PSR-2000/1000 is capable of displaying lyrics
when an XF ﬁle containing lyric data is played.
I 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.

Voice Allocation Format
With MIDI, voices are assigned to speciﬁc numbers,
called "program numbers." The numbering standard
(order of voice allocation) is referred to as the "voice
Voices may not play back as expected unless the voice
allocation format of the song data matches that of the
compatible MIDI device used for playback.
The PSR-2000/1000 is compatible with the following
Even if the devices and data used satisfy all the conditions above,
the data may still not be completely compatible, depending on the
speciﬁcations of the devices and particular data recording
I GM System Level 1
This is one of the most common voice allocation formats.
• Many MIDI devices are compatible with GM System
Level1, as is most commercially available software.
XG is a major enhancement of the GM System Level 1
format, and was developed by Yamaha speciﬁcally to
provide more voices and variations, as well as greater
expressive control over voices and effects, and to ensure
compatibility of data well into the future.
• Song data recorded on the PSR-2000/1000 using
voices in the [XG] category is XG-compatible.
This voice allocation format is compatible with many of
Yamaha's MIDI devices, including the PSR series
instruments.This is also a common format used with
various Yamaha software.
