How to transport #MIDI over #network the easy way? #fedihelp

So, my client just called me, and it turns out… I need to have his MIDI signal from stage at my #FOH, which is around 40m of cable.

I got a CAT cable running with TCP/IP infrastructure anyways.

I know that #RTPMIDI exists, but I never have used it.

So I need something that takes #USBMIDI and makes it available 40 meters somewhere else. Or I need to send USB over 40 meters, doesn't really matter.

I think the endpoint for the MIDI transmission will be VCV Rack on Linux.

Must happen the day after tomorrow, so buying something is not a solution.

I have available: 1 Ubuntu Studio 24.4 laptop. 1 Windows 10 laptop. 1 MacBook Pro 2017. Several iPads, something Bluetooth-MIDI working with one of the iPads.

I used to have #midimonster but it cannot be installed on Ubuntu any more due to dependency shit.

EDIT: See my own answer in 🧵 for a solution.
