The CSNG format contains MIDI data. It appears in Metroid Prime 1 and 2. It is essentially MusyX's SON music format, with a custom header.

This 0x14-byte header isn't part of the MusyX format; it appears at the start of the file. After parsing this the rest of the file is copied into a buffer and then passed to the MusyX functions.

0x0 4 Magic; (always 0x2)
0x4 4 Sequence Index
0x8 4 Voice Count
0xC 4 AGSC ID
