The DDK-7 is compatible with the following formats.
“GM (General MIDI)” is one of the most common Voice allocation formats. “GM System
Level 2” is a standard specification that enhances the original “GM” and improves Song data
compatibility. It provides for increased polyphony, greater Voice selection, expanded Voice
parameters, and integrated effect processing.
XG is a major enhancement of the GM System Level 1 format, and was developed by Yamaha
specifically to provide more Voices and variations, as well as greater expressive control over
Voices and effects, and to ensure compatibility of data well into the future.
GS was developed by the Roland Corporation. In the same way as Yamaha XG, GS is a major
enhancement of the GM specifically to provide more Voices and Drum kits and their variations,
as well as greater expressive control over Voices and effects.
The Style File Format combines all of Yamaha’s auto accompaniment know-how into a single
unified format.
