JENS | OSC Libraries

What are OSC Libraries?

OSC Libraries are pre-built collections of OSC commands for specific software. Instead of manually typing each OSC address, you can import a library and instantly get a full command tree ready to use with JENS.

To import a library, download the .json file below, then go to Settings → Libraries → Import in JENS and select the file.

Create Your Own

You can create custom libraries for any OSC-compatible software. A library is a single .json file with the following structure:

{
  "id": "my-software",
  "meta": {
    "name": "My Software",
    "version": "1.0",
    "author": "Your Name",
    "port_default": 8000,
    "description": "A short description of this library."
  },
  "tree": {
    "label": "Root",
    "children": [
      {
        "label": "Category",
        "children": [
          {
            "label": "Volume",
            "command": {
              "path": "/mixer/volume",
              "args": [{ "type": "float", "range": [0.0, 1.0], "default": 1.0 }],
              "description": "Master volume level"
            }
          },
          {
            "label": "Pan",
            "command": {
              "path": "/mixer/pan",
              "args": [{ "type": "float", "range": [0.0, 1.0], "default": 0.5 }],
              "description": "Stereo pan position"
            }
          }
        ]
      }
    ]
  }
}

Field	Required	Description
id	Yes	Unique identifier for the library (kebab-case)
meta.name	Yes	Display name shown in JENS
meta.version	Yes	Version string (e.g. "1.0", "7.x")
meta.author	No	Author name
meta.port_default	No	Default OSC port for this software
meta.description	No	Short description of the library
tree	Yes	Root node of the command tree
tree.label	Yes	Display name of the node
tree.children	-	Array of child nodes (folder structure)
tree.command	-	OSC command object with path, args, and description

Each node in tree has either children (making it a folder) or command (making it a leaf command). You can nest folders as deep as you like.
