SEQ file format is used by PowerTracks and PowerTracks Pro software applications. PowerTracks is a workstation which allows the user to compose audio tracks and produce music.

The workstation uses project based working technique and each separate music file under production is saved in separate project file. The main purpose of project file is to save all the user applied and added details so that the user can not only keep the track of the progress but can also change any specific action to the main audio data. All the audio data along with the different tools applied with their added effects are stored in the SEQ project file.
