Hello I'm working on a project that transfers MQTT events i to a virtual piano did anyone have a examble flow to connect node red midi to a virtual piano ?

Did this post in your other thread not help: How can i use the node-red command line? - #5 by Steve-Mcl Also, there are a few more midi packages on npm. This one looks decent and has node-js examples: jzz - npm Remember, as i said in other thread, these are NOT node-red "ready" nodes but are node …

@ steve-Mci, yes the mentioned thread did help. i was able to install the midi input output... search now for a virtual midi connection flow

[image] prato: search now for a virtual midi connection flow 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 node-red-contrib-midi works fine.... but a virtual connection to a sofware piano would helpful for my project. example https://vmpk.sourceforge.io/

Have you tried the built in example and read the built in help? Use CTRL+I → examples → node-red-contrib-midi to access examples

You will need a virtual midi driver in order to communicate between software on Windows. This one is the most popular: https://www.tobias-erichsen.de/software/virtualmidi.html

Note: loop midi (by the same author) might be easier: https://www.tobias-erichsen.de/software/loopmidi.html

@niecaude thank you .... just installed . but found in Node Red Midi out no connection to the Virtual Midi Port (loopmidi)

Does it appear in the midi in ?

No ..... appear only a List with Midi Through RtMidi outpit clients but not the in Virtual Piano selected loopMIDI Port
