What is an SYX file?

A SYX file is a MIDI System Exclusive (SysEx) message. Computers use SYX files to communicate with MIDI devices. For example, a synthesizer user might use a SYX file to back up patches stored on a synthesizer to their computer's hard drive.

More Information

Unlike other types of MIDI message files, SysEx messages' format vary from manufacturer to manufacturer and device to device. This means a SYX file that works with one type of MIDI device may not work with another.

However, this format variability also allows users to use SYX files for many different purposes. For example, users can use SYX files to back up data from atypical devices, such as MIDI-compliant lighting controllers, or transmit firmware updates.

How to open an SYX file

You can use Snoize Sysex Librarian (Mac) or MIDI-OX (Windows) to manage SYX files, including recording incoming SysEx messages to SYX files and transmitting SYX files to compatible MIDI-compliant devices.
