BFSEQ (Binary CaFe SEQuence) is a sub file format found in BFSAR files from games like Mario Kart 8. It corresponds to the music data represented in a MIDI-like file, but in binary. Commands that process changes in attributes such as sound generation and volume change over time are described on this kind of file. Since the sequence data is simply a set of commands, sounds are actually producing using bank data (stored in BFBNK sub files) that corresponds to the sound source data.

| 0x07 | UInt16 | Length of this header in bytes. |
| 0x0E | UInt16 | Number of sections. |
| 0x1B | UInt32 | Offset to DATA section. |
| 0x1E | UInt32 | Length of DATA section. |
| 0x26 | UInt32 | Offset to LABL section. |
| 0x2A | UInt32 | Length of LABL section. |
DATA
