What is MIDI?

Instrument with	Other Devices
Using Your

Example: Recording a performance with the auto accompaniment (Style playback) sound of the instrument to an external sequencer

	MIDI cable
PSR-OR700 track (channel)		External sequencer
RIGHT 1	Channel 1
RIGHT 2	Channel 2	Track 2
LEFT	Channel 3	Track 3
STYLE instrument	Channel 4	Track 4

STYLE instrument	Channel 6	Track 6
STYLE instrument	Channel 7	Track 7
STYLE instrument	Channel 8	Track 8
STYLE instrument	Channel 9	Track 9

STYLE instrument	Channel 11	Track 11

As you can see, it is essential to determine which data is to be sent over which MIDI channel when transmitting MIDI data (page 180).

The instrument also allows you to determine how the received data is played back (page 181).

System Messages

This is data that is used in common by the entire MIDI system. These include System Exclusive messages for transferring data unique to each instrument manufacturer and Realtime messages for controlling the MIDI device.

Message Name	Operation/Panel Setting
System Exclusive	Effect type settings (Mixing Console),
Message	etc.
Realtime Messages	Clock setting,
	Start/stop operation

The messages transmitted/received by the PSR-OR700 are shown in the MIDI Data Format and MIDI Implementation Chart in the Data List. The Data List is available at the Yamaha website. (See page 5.)

What You Can Do With MIDI

■Record your performance data (1–16 channels) using the auto accompaniment features on an external sequencer (or computer with sequencer software). After recording, edit the data with the sequencer, then play it back on the instrument.

When you want to use the instrument as an XG-compatible multi-timbral tone generator, set the receive part for MIDI channels 1-16 to “SONG” in MIDI/USB 1 in MIDI Receive (page 181).

MIDI Data Compatibility

This section covers basic information on data compati- bility: whether or not other MIDI devices can playback the data recorded by PSR-OR700, and whether or not the PSR-OR700 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.

Sequence Formats

Song data is recorded and stored in a variety of different systems, referred to as “sequence formats.”

Playback is only possible when the sequence format of the Song data matches that of the MIDI device. The PSR-OR700 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-OR700 is compatible with both Format 0 and Format 1.

•Song data recorded on the PSR-OR700 is automati- cally saved as SMF Format 0.

●ESEQ

This sequence format is compatible with many of Yamaha’s MIDI devices, including the PSR-S900/S700 series instruments. This is a common format used with various Yamaha software.

• The PSR-OR700 is compatible with ESEQ.

●XF

The Yamaha XF format enhances the SMF (Standard MIDI File) format with greater functionality and open- ended expandability for the future. The PSR-OR700 is capable of displaying lyrics when an XF file containing lyric data is played. (SMF is the most common format used for MIDI sequence files. The PSR-OR700 is compatible with SMF Formats 0 and 1, and records “song” data using SMF Format 0.)

●Style File

The Style File Format (SFF) combines all of Yamaha’s auto accompaniment know-how into a single unified format.
