This section covers basic information on data compatibility: whether or not other MIDI devices
can playback the data recorded by 9000Pro, and whether or not the 9000Pro can playback com-
mercially 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.
■ Sequence format
“Sequence format” refers to the way in which MIDI data (for playback, such as songs and styles)
is stored to disk. A number of popular sequence formats described below are compatible with
the 9000Pro.
Playback is only possible when the sequence format of the disk matches that of the MIDI device.
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 9000Pro is compatible with both Format 0 and Format 1.
• Song data recorded on the 9000Pro is automatically recorded as 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.
• The 9000Pro is compatible with ESEQ.
XF
The Yamaha XF format enhances the SMF (Standard MIDI File) strandard with greater functional-
ity and open-ended expandability for the future.
• The 9000 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 conver-
sion system to provide high-quality automatic accompaniment based on a wide range of chord
types.
• The 9000Pro uses the SFF internally, reads optional SFF style disks, and creates SFF styles
using the Style recording feature.
■ 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.
GM System Level 1
This is one of the most common voice allocation formats.
Many MIDI devices are compatible with GM System Level 1, as is most commercially
available software.
• The 9000Pro is compatible with GM System Level 1.
XG
XG is a major enhancement of the GM System Level 1 format, and has been developed
by Yamaha specifically to provide 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.
• The 9000Pro is compatible with XG.
DOC
This voice allocation format is compaible with many of Yamaha’s MIDI devices, including
the Clavinova series instruments.
This is also a common format used with various Yamaha software.
• The 9000Pro is compatible with DOC.
MIDI Data Compatibility
• Even if the devices and data
used satisfy all the conditions
above, keep in mind that the
sounds may differ slightly,
depending on the particular
MIDI device used for playback
(this includes the 9000Pro).
