Download ESP Source Code

ESP is a free, open-source program that can be modified by any experienced programmer. The current version of ESP is 4.0.

To modify ESP, you'll need a computer running Linux. To modify ESP Desktop, you'll need a Linux computer (for common components) and a Windows computer with Visual Studio.NET (for the Windows-specific parts). See the documentation section "Modifying ESP" for the full requirements for programmers.

Remember, you don't have to be a programmer to configure and use ESP and create your own experiments. The source code is needed only for changing the internals of ESP, ESPPrefs, and ESP Desktop.
