rtpmidid[1]. After getting some hardware synthesizers and wanting to connect them without using a computer.. but being able to use them too using the computer I stumbled upon with rtpmidi the protocol and it ticked all the boxes I needed. I could connect all my gear to a raspberry pi, use ALSA sequencer to connect devices to each other with another of my programs AseqRC[2], and then use my synths from my DAW without touching any cable.

So after a fast prototype I created rtpmidid and I'm quite happy on how it works.

And it also helps with the USB ground loop noise that it seems unavoidable some times.

For some time I had even two Orange Pis connected to two sections of my gear, using USB gadget support so my MPC One could speak rtpmidi. MPC One has support to connect as host to MIDI devices, but as guest (connect to the computer) only in controlled mode which is not what I needed to convert my MIDI tracks to my DAW.
