THE GENERAL MIDI (GM) MODE
...............................................................................................................................
In this mode MIDI data is received and transmitted in accordance with the General MIDI
System Level 1 standard. General MIDI data can be received via the MIDI IN
connector and played by the PSR-6000. General MIDI data transmitted via the PSR-6000
MIDI OUT connector can be used to control appropriate tone generators and other MIDI
equipment.
For details refer to the “MIDI Function Tree” on page 128, the “Voice List” on page 116,
and the “GM/DOC Mode Percussion Map” on page 121.
3 Ways To Select the GENERAL MIDI Mode
• Insert a General MIDI disk (the GM mode is automatically selected).
• Press the [DISK ORCHESTRA/GENERAL MIDI] button.
• Receive a MIDI exclusive “Switch To GM Mode” message from an external MIDI
device.

ABOUT GENERAL MIDI
The existing MIDI protocol allows performance and other data to be transferred between different instru-
ments, even if they are from different manufacturers. This means, for example, that sequence data that was
originally created to control a tone generator from manufacturer A can also be used to control a different tone
generator from manufacturer B. Since the voice allocation in different devices from different manufacturers is
usually different, however, appropriate program change data must be transmitted to select the right voices.
The General MIDI protocol was developed to minimize confusion and the need for re-programming when
playing software created by one MIDI device on another. This has been achieved by defining a standard voice
allocation in which the same or similar voices are accessed by the same program change numbers or MIDI
channels. The current standard recognized by the International MIDI Association is known as “GM System
Level 1.” The PSR-6000 voice allocation complies with the GM System Level 1 standard when it is switched to
the GM mode. See the “Voice List” on page 116 for details.
