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.

🧵 So: How to transport #MIDI over #network the easy way?

The easy way is supposed to be #RtpMidi, which is built into #macOS / #OSX.

On #Linux, there is #rtpmidid, which I didn't try as it says it is alpha software. rtpMidi by MacLarenLabs does it for 12$: https://mclarenlabs.com

It does communicate successfully with #macOS.

For #Windows, there is another software also called rtpMIDI by Tobias Erichsen which I didn't try… https://www.tobias-erichsen.de/software/rtpmidi.html

It turns out however that OS X #Monterey cannot route MIDI from a USB MIDI Interface into RtpMidi. It is supposed to, but it just doesn't work, and it doesn't say anything about it.

The workaround with OS X on the sender side is to run #Ardour as a MIDI router on it using a #MidiBus.

And for those wondering what I actually have to do in the project?:

I will have a plant that is hooked up to a device creating sounds plus MIDI events and I need to create DMX lighting events from these. So the plant will make sound and light.

🧵 So for weirdness' sake, here is the #vcvRack patch that takes #MIDI data via #rtpMidi, running on #UbuntuStudio #Linux, fed from #MacOS / #OSX over the network…

… doing some weird things with MIDI notes, and then outputting MIDI CV to #MidiMonster which creates #ArtNet networking messages from it…

… which then are converted to a #DMX signal in an #XLR cable usind a #ShowTec #Net23 ArtNet-Node.

@nielso I have no idea what this really does, but I love everything about it!

Basically it is crazy mapping of MIDI notes to RGB values. Low notes will be green, high notes blue, and everything in between some mixture. The RGB values get send out as MIDI CC to midimonster, which converts them to DMX light control messages encapsulated in ArtNet (DMX via TCP/UDP).

This could perhaps even be done with midimonster alone, but I had done a simple prototype in vcvRack already, so I built on this.

@nielso @mosgaard I would be keen to hear how it sounds!

It doesn't sound at all. It's just controlling lights.

The MIDI input data were coming from a Pocket Scíon "listening" to a plant and also creating sounds directly.

I'm not so much sure what this product actually does and how much of it is really coming from the electric resistance of the plant. It sounds pretty much the same when you "measure" your body or a filet of dead fish I suppose.
