• Format type (0=single track, 1=multi-track, 2=independent tracks)
• Track count
• Tempo (BPM from meta event 0x51)
• Time signature (from meta event 0x58)
• Note count (total note-on events)
• Duration (in seconds, computed from tempo + tick count)
• Key signature (from meta event 0x59)
• Track names (from meta event 0x03)
