Elixir Source Code File

An EXS file may also be a source code file written in the Elixir programming language. It contains code that a software application uses to perform Elixir-related functions. EXS files can be opened in any text or source code editor.

Elixir is a functional , concurrent programming language based on the Erlang programming language. Developers use Elixir to create scalable, distributed, and fault-tolerant applications. Discord, FarmBot, and Brex all use Elixir in their applications.

When a developer uses Elixir to develop an application, they save the application's Elixir-related code in .ex and EXS files. By default, Elixir creates a series of EXS files when a developer invokes the mix new command to create a new Elixir application. These EXS files include a project configuration file, named mix.exs , and formatting and application test files.

mix.exs - An Elixir application's project configuration file.

appname_text.exs - A test script used to test an Elixir application.

You can open and edit EXS files in any text or source code editor, including:

In order to compile or run the Elixir code an EXS file contains, you must install Elixir (cross-platform).

EXS Instrument

An EXS file may also be an instrument used by Logic Pro, a digital audio workstation (DAW). It contains an instrument, which includes information referenced by Logic to play an audio sample according to its type, such as a piano, guitar, or drums.

EXS files are used by EXS24, a sampler library that comes included with Logic Pro X. The library contains a large collection of samples such as strings, brass, synth textures, and pianos. EXS24 can be used to arrange sounds you recorded yourself or that were already recorded to be played back from a MIDI track within Logic or from your MIDI keyboard.

EXS files are located in the "Sampler Instruments" and the "EXS Factory Samples" folders in the "Logic" folder on your hard drive. A "Samples" folder is also located in the "Logic" folder and it contains audio files, such as .WAV or .AIF files, that are referenced by Logic when playing the associated EXS file. You can add EXS instruments to these folders, which will then appear in the instruments menu in Logic. If Logic is open when you add the instrument you need to refresh the menu in order for the instrument to appear.
