Did this post in your other thread not help: [How can i use the node-red command line? - #5 by Steve-Mcl](https://discourse.nodered.org/t/how-can-i-use-the-node-red-command-line/57017/5)

Also, there are a few more midi packages on npm. This one looks decent and has `node-js` examples: [jzz - npm](https://www.npmjs.com/package/jzz)

Remember, as i said in other thread, these are NOT node-red "ready" nodes but are node modules. You can install and use a regular node module in a function node by `import`ing it in the `setup` tab of the function node.

See node-red docs on [importing using a regular node module in a function node](https://nodered.org/docs/user-guide/writing-functions#loading-additional-modules)

Are we talking about a module or did you install a node-red midi node?

Which node are you trying to use?

sorry for my bad english. . i have install the

Have you tried the built in **example** and read the **built in help**?

Use

You will need a virtual midi driver in order to communicate between software on Windows.  
This one is the most popular:

Note: loop midi (by the same author) might be easier:

Did you try the node-red-contrib-midi-windows node ?  
The original one is not maintained anymore sadly, it does work on Windows but perhaps the Windows specific one will work with Virtual ports ?

</div>

yes.... i have already the node-red-contrib-midi-windows in use.. try different settings without success at the moment

i tried to connect via UDP, now i realize . My Node Red runs on a external Linux/Ubuntu server, so of course Node Red can't use the Windows Midi ports. 😵
