Impulse Tracker is a multi-track digital sound tracker (music sequencer). Originally released in 1995 by Jeffrey Lim as Freeware with commercial extensions, it was one of the last tracker programs for the DOS platform.

In 2014, on its 20th anniversary, Impulse Tracker became open-source software and the source code was released.

Impulse Tracker was authored by Jeffrey "Pulse" Lim for the DOS/x86-PC platform.[2] Impulse Tracker was coded in Assembly language, and the GUI was heavily influenced by that of Scream Tracker 3.

The first version was released in 1995 and included example music, provided by Jeffrey Lim and Chris Jarvis. The software was distributed as freeware, though extra features, such as support for stereo WAV output and a personalized version of the driver for co-editing songs over IPX networks, were provided for a fee. After the stereo WAV writer plugin was publicly pirated,[5] the original author announced that he would discontinue development after version 2.14. The latest version was v2.14 Patch #5 released on April 8, 1999.

On February 16, 2014, Jeffrey Lim announced that he would release the complete source code of Impulse Tracker as part of its 20-year anniversary. On October 19, 2014, the first part of the source code was released on a Bitbucket repository. On December 25, 2014, the missing parts (sound drivers) were added and the code was officially released under the BSD license.


Like in most module editors, music is arranged on a grid of channels. Each supports note on and note off instructions similar to MIDI. Impulse Tracker modules use the .IT file extension.

New Note Actions (NNAs) is a feature that handles commands received on the same channel as another instrument which is still playing. NNAs allow the user to customize the subsequent action:

Cut: The new instrument replaces the current instrument.
Continue: The old instrument continues to play using its ADSR curve.
Off: The old instrument begins the release section of its ADSR curve.
Fade: The old instrument fades out to 0 volume at a designated rate overriding the ADSR curve.

Impulse Tracker supports hardware MIDI channels on the Gravis Ultrasound, InterWave and Sound Blaster 32 card families (provided enough RAM is available).

IT file format

The .IT file format is the format native to Impulse Tracker. It is similar to older formats such as .MOD, but features new additions such as new note actions which allow the user to customize subsequent actions on receiving commands from the same channel as the one playing.

Some[which?] player software supports the .ITZ format, which is a renamed zip file that contains a .IT file.
