Full Raspberry Pi 4 Eurorack module with touch screen
Hey folks,
I have been looking in to good alternatives for a eurorack raspberry pi module. When I came across this... it is a DIY kit for assembling RPi into eurorack modular system with 5" touchscreen LCD, Audio, MIDI and 16-pin power interfaces.
Ideally I would like to have RNBO support for a dedicated audio device like a Daiseypatch (*cough cough Cycling74*). But this eurorack module is pretty intriguing, especially the touch screen display. It would be great to be able to use it to create as many knobs and sliders as I wanted to control my Max patch. 26HP is a lot or eurorack real estate, but if I can configure it any way I want it would be worth it.
My question would be would the Cycling74 raspi image work on this hardware and would it need any additional drivers? There are additional ports on the faceplate, how would you access these from RNBO?
It would be great to know if anyone else has discovered this and tried building it.
Can anyone at Cycling give me some insight on whether of not RNBO patches would run on this raspi OS image? Would additional driver be needed? How would I access the ports? Does RNBO support full display of controls on the touch screen?
The program that we use for the RPI doesn't have any display support, but you could write your own.
For reference, this is what is on the RPI: https://github.com/Cycling74/rnbo.oscquery.runner
It looks like they're suggesting that you use `Patchbox` which we don't support directly, but you should be able to build the runner for, since it is using apt-get, you might even be able to simply add our apt repo and use our pre-built binaries.
If you want to use the RPI image that we provide, you'll likely have to ssh into the device and setup the audio interface, but that looks relatively simple: https://raw.githubusercontent.com/Deftaudio/Midi-boards/master/Eurorack_RPi/Eurorack_RPi_synth_kit_software_installation.pdf
It doesn't look like you need any special drivers, you simply need to configure the kernel for the audio and midi devices.
So in short. I believe you can get this working but it'll take a little bit of effort on your end.
I've got the RNBO runner working on Patchbox OS, you can find the steps here:

Excellent, thanks for the info share Maciek
Thank you for your feedback. I would rather not mess with Patchbox, I would prefer just to run my RNBO patch on the device.
I think ideally I want to be able to utilize the full touch screen display, that is kinda the whole point of going through the trouble of putting this together, which will take quite a bit of effort for me.
But it is good to know how to get RNBO patch to work in Patchbox so that I have an alternative.
Alex, thank you for your pointers, I will try to get the display and audio interface working, once I get all the parts and put it together. Will keep you posted.
Another question, if I use the C74 raspi image, how would I access the hardware ports on the front from RNBO?
