General MIDI Level 2
General MIDI Level 2，簡稱GM2，是MIDI的標準規格。它的基礎是General MIDI以及GS extensions。在1999年由MIDI製造商協會(MMA)所採用。
最低需求條件
- 同時發聲數：32
- MIDI頻道：16
- 同時演奏旋律樂器達16個（所有頻道）
- 同時演奏打擊樂器組達2組（頻道10/11）
參數
音色及群組轉換事件（Program and bank change events）
General MIDI 2相容的合成器透過設定cc#0 (Bank Select MSB)至121並使用cc#32 (Bank Select LSB)在音色轉換之前去選定各個群組。群組0包含了原本GM中所有的聲音組。
