General MIDI Level 2

From Wikipedia, the free encyclopedia

General MIDI Level 2 or GM2 is a specification for synthesizers which defines several requirements beyond the more abstract MIDI standard and is based on General MIDI, GS extensions, and XG extensions. It was adopted in 1999 by the MIDI Manufacturers Association (MMA).

• Number of Notes: 32 simultaneous notes
• MIDI Channels: 16
• Simultaneous Melodic Instruments – up to 16 (all Channels)
• Simultaneous Percussion Kits – up to 2 (Channel 10/11)

General MIDI 2 compatible synthesizers access all of the 256 instruments by setting cc#0 (Bank Select MSB) to 121 and using cc#32 (Bank Select LSB) to select the variation bank before a Program Change. Variation bank 0 contains the full GM — that is, General MIDI 1 — sound set. Variations using other bank numbers are new to General MIDI 2, and correspond to variation sounds introduced in Roland GS and Yamaha XG.
