Data Compatibility
This section covers basic information on data compatibility: whether or not other MIDI devices can playback the
data recorded by CLP-280/270, and whether or not the CLP-280/270 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.
Basic Check Points
The data and the MIDI device must match in regards
to the items below.
• Sequence format
• Voice allocation format
• Disk Format (floppy disk drive is optional)
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 CLP-280/270 is compatible with the following for-
mats.
■ 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 CLP-280/270 is compatible with both Format
0 and Format 1.
• Performance data recorded on the CLP-280/270 is
saved in the SMF format 0.
■ ESEQ
This sequence format is compatible with many of
Yamaha’s MIDI devices, including the Clavinova series
instruments. This is a common format used with various
Yamaha software.
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
allocation format.”
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 CLP-280/270 is compatible with the following for-
mats.
■ GM System Level 1
This is one of the most common voice allocation for-
mats.
Many MIDI devices are compatible with GM System
Level 1, as is most commercially available software.
■ GM System Level 2
“GM System Level 2” is a standard specification hat
enhances the original “GM System Level 1” and improves
song data compatibility. It provides for increased
polyphony, greater voice selection, expanded voice
parameters, and integrated effect processing.
■ XG
XG is a major enhancement of the GM System Level 1
format, and was developed by Yamaha specifically to pro-
vide more voices and variations, as well as greater expres-
sive control over voices and effects, and to ensure
compatibility of data well into the future.
Song data recorded on the CLP-280/270 using voices in
the XG category is XG-compatible.
