Using Your PSR-2100/1100 with Other Devices Voice Allocation Format With MIDI, voices are assigned to specific numbers, called "program numbers." The numbering standard (order of voice allocation) is referred to as the "voice allocation format." Voices may not play back as expected unless the voice allocation format of the song data matches that of the compatible MIDI device used for playback. The PSR-2100/1100 is compatible with the following formats. Even if the devices and data used satisfy all the conditions above, the data may still not be completely compatible, depending on the specifications of the devices and particular data recording methods. ■ GM System Level 1 This is one of the most common voice allocation formats. • Many MIDI devices are compatible with GM System Level1, as is most commercially available software. ■ XG 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. • Song data recorded on the PSR-2100/1100 using voices in the [XG] category is XG-compatible. ■ DOC This voice allocation format is compatible with many of Yamaha's MIDI devices, including the PSR series instruments. This is also a common format used with various Yamaha software. 162 PSR-2100/1100
