What is a .SDX file?

The .SDX file extension is used for a type of file known as Sample MIDI Dump Exchange. This file contains MIDI data that has been "dumped" or extracted from a standard MIDI (.MID) file and then compressed using a system developed by Simmons, known as the SDX system. MIDI files are commonly used to store music data in a format that electronic musical instruments and computers can understand and process.

To open an .SDX file, you can use software programs like FMJ-Software Awave Studio or Apple QuickTime Player, which is included with the macOS operating system. These programs are designed to handle and decode the data contained in .SDX files so that you can work with or listen to the content.

Additionally, an .SDX file might be encountered when you purchase digital content online, such as music or software. In this context, the .SDX file is used in conjunction with Secure Download Manager (SDM), a tool that helps manage and secure the download of your purchased items. When you buy an item and choose to download it, the .SDX file is downloaded to your computer. Opening this file starts the SDM, which then proceeds to download the actual content you purchased.

It's important to note that depending on the web browser you use, the SDM might not automatically open the .SDX file after it's downloaded. If this happens, you'll need to locate the .SDX file in your download folder or wherever you chose to save it and open it manually to start the download process of your purchased item. This process ensures that your download is secure and that the file integrity is maintained.
