Overview
What is an STX file? An STX file is a video project created by Corel Pinnacle Studio video editing software. It contains video project settings and references to media and other data files the project uses. Corel replaced STX files with .AXP files as the default project format, but Pinnacle Studio still supports STX files.
More Information Pinnacle Systems initially developed Pinnacle Studio in the 2000s, which is when the software saved projects as STX files by default. However, Corel eventually acquired Pinnacle Studio in 2012 and replaced the STX format (along with the .SCN and .STU formats) with the AXP format. Since AXP files replaced STX files, the files have become obscure. You will likely only encounter STX files if you are trying to open an old project.

Scream Tracker Music Interface Kit File

An STX file may also be a music module format used by Scream Tracker, a DOS-based music tracking system developed by the demoscene group Future Crew in the early 1990s. It contains music as a combination of digital audio samples, patterns, and playback instructions rather than a single recorded audio stream. This approach lets the tracker recreate the song in real time using small sample files, which was important when storage space and memory were limited.
More Information
Future Crew, the Finnish demoscene group behind Scream Tracker introduced the STX format in the early 1990s as a transitional step between the older .STM (Scream Tracker 2) format and the newer .S3M (Scream Tracker 3) format. It allowed composers to begin using features planned for Scream Tracker 3 while maintaining partial compatibility with earlier tools.
The format supports more flexible channel handling and improved structure compared to STM, but it never became as widely adopted as S3M, which quickly replaced it. Today, you are likely to encounter STX files only in retro music archives or historical collections of tracker modules.
How to open an STX file
You can open and play STX files using modern tracker-compatible players, such as OpenMPT , MikMod , or Vitamin/CAIG ZXTune.
