About General MIDI
General MIDI standardizes MIDI data for all sound source types, regardless of manufacturer. General MIDI
specifies such factors as tone numbering, drum sounds, and available MIDI channels for all sound sources. This
standard makes it possible for all MIDI equipment to reproduce the same nuances when playing General MIDI
data, regardless of the manufacturer of the sound source.
This keyboard supports General MIDI, so it can be used to play commercially available pre-recorded General
MIDI data and General MIDI data send to it from a personal computer.
