Hosting library and audio plugin for JSFX

capture

Description

This package provides support for audio and MIDI effects developed with the JSFX language. These effects exist in source code form, and they are compiled and ran natively by hosting software.

This contains a hosting library, providing a JSFX compiler and runtime. In addition, there is an audio plugin which can act as a JSFX host in a digital audio workstation.

Remarks

Despite what the name might suggest, JSFX is not JavaScript. These technologies are unrelated to each other.

This project is not the work of Cockos, Inc; however, it is based on several free and open source components from the WDL. Originally, this project was based on jsusfx by Pascal Gauthier, but then it became an entire rewrite made from scratch.

Some time after the realization of this project, Cockos announced the release of JSFX as open source under the LGPL. This does not affect the development of this project, which remains a custom implementation based on the liberally licensed bits of the WDL.

Usage notes

The audio plugin will initially present the JSFX effects available in the REAPER user folders, if these exist.

The effects are source code files which end with the extension .jsfx, or with no extension at all.

Note that, unlike REAPER, ysfx will let you install JSFX wherever you want. If you use effects from a custom folder, ysfx will usually figure things out, but not always.

The ideal hierarchy is one where there exists at least a pair of folders named "Effects" and "Data" side-by-side, which receive the code files and resource files respectively.

Building

To build the project, one must first set up a C++ development environment equipped with Git and CMake. One can then build the library and the audio plugin, by entering commands as follows:

git clone https://github.com/jpcima/ysfx.git
cd ysfx
git submodule update --init --recursive
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
cmake --build .
