    : Raw binary files containing data specific to one manufacturer or model.

    In the complex world of digital audio and electronic music production, data is the lifeblood that flows between instruments, computers, and sound modules. For decades, the Musical Instrument Digital Interface (MIDI) has served as the universal language for this communication. However, beneath the standard notes and clock signals lies a deeper layer of data known as System Exclusive (SysEx).

    SysEx messages are manufacturer-specific MIDI messages that begin with F0 (start) and end with F7 (end). Unlike standard MIDI messages (3 bytes max), SysEx can be arbitrarily long and can contain:

    One might assume that converting SYX to MIDI is a straightforward renaming process. It is not. The complexity arises from structure:
