How to install rtpMIDI on RaspberryPi or other Linux SBC

Here are the steps to install rtpMIDI on companion-pi (or any Linux SBC)

  1. Install Companion Pi (or your favourite SBC distro) and get to a terminal window.

  2. At the prompt, enter:

  3. Next:
    sudo dpkg -i rtpmidid_23.12_arm64.deb

  4. Then enter:
    sudo apt -f install

After that, you should see rtpMIDI devices in the MIDI choices.
Note that the rtpMIDI devices are called rtpmidid, NOT RtMidi (which is the companion MIDI library)

Here’s my walkthrough with a fresh install of CompanionPi on an RPI3.

I just wiped and did a fresh install on my CompanionPi (with a backup). I ran your commands and so far they look like they are working! So somehow my install was messed up. It’s working!

Excellent! Was that the beta version of CompanionPI or the stable version?


Also, if I have two CompanionPi’s on the same network doing different things and want them both to have this feature, is there a way to change their advertised name that appears in Mac Audio MIDI setup? I’m concerned right now that I only see one CompanionPi listed and there are two running. I don’t want them both getting all Network MIDI commands if that makes sense.

I think the best way would be to change the hostname of the RPI’s. That way you’ll be able to identify them for ssh and also rtpMIDI. I also don’t know if you can have 2 devices with the same hostname, it MIGHT automatically rename one of them, so better to control that yourself.

Use sudo raspi-config and under “system options”, choose “change hostname”

I renamed mine to companionpi-1 and it shows up like this:

This is so helpful. Thank you!

I sent MIDI over the network directly to the Pi today. It was amazing and will really be interesting now that I can explore this option.

You should get your work baked into the next release of Companion! Would be great if MIDI was available robustly out of the box. And would let you use say a single note with different velocities to trigger buttons on a page. So assign a note per page and then use the velocity.

My two cents! Would be easier than setting up triggers for every button you want to press via MIDI.

I disagree. It’s already as easy as adding the generic-midi module to your config.
Personally, I’d prefer to have a lot of the “extra” stuff that’s in companion put into modules so you can have what you want and keep the base companion simpler. I don’t need X-Keys or ARTnet support, for example.

You can do that already.

How do I do this?
