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.
