Hi, I build a headless zynthyan on my raspberry Raspberry Pi 3 Model B Plus and I would like to add an old line6 toneport kb37 ( Line 6 Legacy Products) i own, as sound card and midi keyboard.
Do you think is possible? Any guide to install it on the raspy and let it use by zynthian?
Hi @nojarec, welcome.
This toneport kb37 looks so sweet, I hope you will get it to work with Zynthian. It’s really in the Zynthian spirit’s imho: compact and versatile …
Usually, most of the USB sound cards are so called “class compliant” wich means pratically : should work out of the box.
So if you already have a running Zynthian OS you can just plug the keyboard and see how Linux reacts (make the use of “demesg” command before and after plugin in the keyboard. If you get some kernel reactions you’re on the good way.
Then use commands “aplay -L”, “arecord -L” to identify the USB peripherical name you will have to use in jackd soundserver configuration.
But before going headless I suggest you to start with a display (any HDMI display is Okay). It’s much more easier to get started this way.
Don’t hesitate to ask for any help when needed.
Yet check and test Zynthian with a hdmi display and now I’m accessing it on wifi
Yesterday Kb37 seems to not to power on when connected to USB (on mac you should install the drivers first to have power on it).
I tried this:
http://www.ubuntugeek.com/how-to-install-a-line6-guitarport-or-toneport-ux1-or-gx.html
and this:
but without success
How can i access jackd soundserver configuration?
This has to be done within webconf under “Hardware audio”.
Did you investigate as I explain above. Having logs from the system will help a lot
Ok, I briefly check the links you’ve provided.
The one on ubuntugeek is really old and not accurate anymore.
But next one is pretty good.
So these Line6 products needs a dedicatd kernel module to be build. You’ve done that but “it doesn’t work”. Okay, but as already said, without some kernel logs it will be hard to debug
Also, check if the kernel module (=driver) you have built is loaded at startup using command “lsmod”
This device is not class compliant so needs drivers to work on any OS. There is a guide here on how to compile drivers for this device on Linux. This guide is for Ubuntu but should work on Zynthian too.
[Edit] The subversion repository for this is no longer valid. I will look to see if it is hosted elsewhere…
Hi @riban , as I understand so far, driver is in linux kernel source but is not available “as is” (precompiled) in RBPi Os.
The driver source is available from Debian repo but does not build on a Raspberry Pi with error:
arch/arm/Makefile:57: *** Recursive variable 'KBUILD_CFLAGS' references itself (eventually). Stop.
I have limited time to look at this and no way to test it. It would be great to add this as a supported device in Zynthian but at the moment it doesn’t work.
No, it’s totally outdated. The INSTALL procedure talk from kernel version 2.6, Zynthian runs 5.10 !
And now the driver is in mainline linux tree, see here: linux/sound/usb/line6 at master · torvalds/linux · GitHub
and is also in the raspberrypi Os: linux/sound/usb/line6 at rpi-5.10.y · raspberrypi/linux · GitHub
And I even found this: Can you please add Toneport UX1 Line 6 driver (USB soundcard) into kernel? · Issue #4562 · raspberrypi/linux · GitHub
so since the 3th of september, a simple apt upgrade or apt dist-upgrade could do the trick ?
Nope! Although the repo is available, I tried to compile from it with errors. It may be the same repo from which the Debian source package is derived which also fails to compile.
On the other hand…

This suggests that Zynthian should support the Line6 device but the driver may need to be loaded.
Please open a terminal on the Zynthian and run dmesg -w to start the kernel logger output then plug in the device and paste the resulting output here.
You can then remove the device, run the command modprobe snd-usb-line6, run dmesg -w, plug in the device and paste the resulting output here.
You may then run aplay -l (that is a lower case L) and paste the result here.
yeah !

I don’t think you needed to recompile the kernel. You will see in my last post that these drivers are already part of the ZynthianOS distribution. Hopefully you haven’t broken anything else in the kernel. (I tend to find that happens when I compile a kernel!)
Well done for getting the audio working but it is odd that you need to reassert the USB config each boot. Are you able to test this with the stock ZynthianOS image?
It would be good to get the audio working out-of-the-box and then look at MIDI.
I worked on the ZynthiaOS image. I’m testing on ZynthianOS
Yes, but you then recompiled the kernel. I expect this should work with the stock ZynthianOS kernel and would like to know its behaviour without changing the kernel.
