IT File – What is .it file and how to open it?

IT File: Format and Structure

An IT file, also known as an Impulse Tracker Module, is a music file format used by the Impulse Tracker software. It contains musical data organized into patterns and orders, allowing users to create and edit complex musical compositions. Patterns represent individual sections of music, while orders determine the sequence in which patterns are played. IT files support up to 64 channels, each of which can play a different instrument or melody. Additionally, IT files can include various effects, such as panning, volume control, and pitch bending, enabling musicians to add depth and nuance to their tracks.

Compatibility and Applications

IT files are primarily associated with the Impulse Tracker software, a popular music tracker application used in the late 1990s and early 2000s. However, due to its widespread use, IT files have become compatible with numerous other music software programs, including Renoise, MilkyTracker, and OpenMPT. This compatibility has allowed IT files to remain a popular format for sharing and archiving music, particularly in the electronic dance music and chiptune communities. Despite the availability of more modern music formats, IT files continue to be valued by musicians who appreciate their flexibility, modularity, and legacy within the music production world.

IT File Characteristics

IT files store digital audio data in the Impulse Tracker Module format. This format is commonly associated with the Impulse Tracker software, a music tracker used for creating and editing music. IT files contain musical patterns, instruments, samples, and other data necessary for music production. Due to their compact size and efficient organization, IT files were widely used in the demo scene and electronic music production.

Opening IT Files

To open an IT file, you will need to use a compatible software application. Several options are available for different operating systems:

• Windows: Impulse Tracker (original software), OpenMPT (open source), MilkyTracker (freeware)
• MacOS: MilkyTracker (freeware)
• Linux: OpenMPT (open source), MilkyTracker (freeware)

Once you have installed the appropriate software, you can open an IT file by dragging and dropping it onto the application’s interface or by using the “Open” command from within the software. After opening, the IT file’s musical data can be viewed, edited, and played back using the features provided by the software.

Impulse Tracker Module (.IT) File Format

The Impulse Tracker Module (.IT) file format is a digital audio format developed by Jeffrey Lim, the creator of the music tracker software Impulse Tracker. It was primarily intended for use in tracking music on Amiga computers in the early 1990s. The .IT format stores musical data in a module-based structure, which consists of patterns, instruments, and samples. Each pattern contains a series of musical events, including note data, instrument assignments, and effects. Instruments define the sound characteristics, such as sample mapping, pitch envelopes, and volume settings. Samples are typically raw audio data in various formats, such as PCM or ADPCM.

The .IT format is known for its robust pattern-based editing interface, which allows for precise control over the arrangement and sequencing of music. It also supports a wide range of sound effects and instrument parameters, providing musicians with a versatile tool for creating complex and dynamic music. The format gained popularity in the Amiga music scene and was subsequently adopted by other tracker software, becoming one of the most widely used module formats in the early days of electronic music production.
