Questions about zynthian OS automated build system

[le51]

I have forgot that feature hahaha
Thank you @jofemodo, I will investigate that when I’ll be back home (after 15 days of containment at my girlfriend’s home -frankly not that bad - but far from my SBC and my musical gear).

[guysoft]

Hey @le51 I am the creator and maintainer of CustomPiOS which is the system used to build Zynthian’s OS (we call those scripts ZynthianOS).

CustomPiOS supports changing the base image that the build is based off which was intentionally done so you can support other SBCs.
I haven’t had much cooperation maintaining other devices and would welcome and help if I can getting other machines to support Zynthian and other distro builds.

Also I see you mentioned armbian, there is an armbian build variant. But it needs more love and caring. There is an “ubuntu base image” switch too, which I started adding to the devel branch of CustomPiOS.

[guysoft]

@le51

• what are base files that are used for that (github repo from github.com/zynthian ?)
• is raspbian buster minimal image the startpoint ?
• is the build done on a cloud instance ?
• how to automate that ?

• Zynthian uses ZynthianOS: GitHub - zynthian/ZynthianOS: Disto to build a Zynthian image ready to ship
• Yes but you could adapt it to any base image, we use rasbian because it has non-free drivers we want to have available.
• Yes, we use Jenkins that executes a docker instance of CustomPiOS
• Yes, there is a nightly build. Best method is to have Jenkins that can run docker commands, from there just follow the instructions. I can throw in our jenkins shell script:

Hi Guy, thank you for your input.

I’m now back at my home.

Firstly, I will try to build zynthian step by step on the nanopi m4v2 itself (wich is much more powerfull than the nanoPiK1plus, with its Nvme HD and 4 Go ram), starting from the armbian server image and using the script

setup_system_rbpi_raspbian_lite_buster.sh

Then, if I’am successfull with this (<=> having an armbian adapted setup_system script), I’ll go further in automation (as I’m pretty new with these docker/jenkins stuff).

[xanderz]

Sorry to revive this thread, but have you got anywhere?
I am also thinking on building zynthian over armbian for H3 (Orange Pi PC plus).
Are there any Raspbian-specific dependencies that would otherwise be a bottleneck in building zynthian for H3?

I think this isn’t a very straightforward process, but are there any hints/tips for porting zynthian to other platforms?

[le51]

Hi @xanderz ,

@xanderz

building zynthian for H3?

it’s not an easy task. A full ZynthianOs is a bunch of Gb of a “working” software stack (raspi base system wich is based on debian, with the help of kxstudio and maybe other deb repo and of course all the apps that are build from source -see here- with everything encapsulated in Zynthian sofware/UI/hardware).
Maybe this could help:

Success Cases

Hi @rozhok , you will have to build the Zynthian software by your own using as starting point the minimal Armbian debian buster image. (You have to scroll down at the bittom of the page ti find the download link). Then you have to follow all the steps as mentioned in the setup script (and all the others scripts that are called by the setup script). Some adjustments are needed (remove some specific raspberry pi stuff like firmwares) as in the envars file where compilation flags have to been …

[xanderz]

Got it.
But is there anyone around that tried running zynthian on H3 with 1GB of RAM(or at least, similar hardware)?
I honestly am afraid of spending lots of hours in porting zynthian and then finding out that the hardware is crap and has lots of lag.
I would have bought a RPi 3/4 if I can damn find at least one in any store in Romania(chip shortage issue maybe?).
Digikey, Mouser and such have tens of weeks lead time…

[riban]

@xanderz you will have hours of toil to port Zynthian to any other platform with no guarantee it will work properly, if at all. I would not even attempt this unless I had the device and lots of time. 1 GB RAM will be a limiting factor. It can really slow down compilation of code. Chip shortage is a real pain affecting almost all technology delivery but if you get a chance, try to get a Raspberry Pi 4 (2GB or larger). You can sometimes find vendors selling their own kits with larger RAM units, PSU, etc. for a good deal. Keep looking my friend .

[le51]

I agree with @riban
It took me hours (days ?) to build Zynthian on a H5 board equiped with 2Gb ram and 32Gb of emmc drive.
I achieved to make the dac to work (with pcm5102 chip) and the UI to get up. But most of the software instruments where buggy (100% of cpu load, interface freezing, application crash and so on).

[Baggypants]

The very first thing you should test is the audio ability.
Start with whatever debian based os works for the board. add the kxstudio repos and install something like setBfree or Fluidsynth. Get Jackd running with whatever alsa device is reported, plug it all together with qjackctl, patchage or something and give it a quick run with a usb midi keyboard. I’ve done this sort.of thing on the pinephone or pinebook pro and it will give you a good view of how it will manage with audio output capability, or xruns and stuff.

IF it works really well then try git cloning all the zynthian stuff on top of the build and see what runs. I also did that with Fedora on a laptop before I got a zynthian kit. It’s terrible but.can get you off the ground.

[xanderz]

@riban There are very few resellers, and they are selling really overpriced raspberry pi4s for which money I can easily buy a used Thinkpad with an i5/i7 that can easily run any vst.
But this defeats the whole purpose of having a fully-embedded, small form factor synthesizer.

@Baggypants thanks for the tips, will try that today and see how it goes. Maybe also patch the kernel to use the RT patch and see if it helps in any way.

I’m planning to get the most barebone armbian image and work from there.
I think I will scrap the on-board compilation idea and go with docker as I have more than decent computer to handle the build

[riban]

Realtime kernel is not advantageous and generally gives worse performance. Low latency kernel is important.

[xanderz]

@Baggypants so I just installed fluidsynth and got a relatively lightweight soundfont(~12MB).
I am really impressed with the performance. The lag is quite small(I can notice it, but it’s very small indeed).
Owning a Korg PA1X they are very close in terms of responsiveness.
No xruns displayed, but I might want to load it a bit more with a beefier soundfont.

[Baggypants]

Excellent news! Mess with the jack settings to get lower latency with potentially more xruns. There will be a sweet spot somewhere.

For a beefier synth try ob-xd and one of the massive pads. You will need to launch it using jalv. Beyond that there’s Surge synth.

[xanderz]

Ok, so I went headfirst and try building zynthian on my orange pi. Removed some lines from the install scripts which were raspberry-specific(wiring being one of them).
Script ran fine, but did not manage to see any ouput because I left it running and when I came back to it, it already finished and closed the screen made when I launched the setup script. So I guess, if there are no logs saved, I can’t know what went wrong.
Anyways, rebooted the board, and hdmi displayed the armbian boot sequence then an error about /sda/fdb1 or something like that. I guess, for the moment, since I don’t have a SPI screen on-hand, I will try to use HDMI (found out on the forum that it is possible to do so).
I wanted to change the hardware settings using the webconf tool, but it doesn’t work. Tried manually launching it with the script and I get all sorts of errors of missing modules in python. So I’m manually installing them, but this is clear that the setup script failed one way or another.
Nevertheless, here’s a snip over ssh. Looks like some parts of zynthian are actually configured:

[xanderz]

Ok, so upon further investigation and manually installing python modules, I can’t seem to be able to install patchage, nor find it on pypi.org

[wyleu]

patchage isn’t python to my knowledge it’s a system based install
sudo apt install patchage or similar.

http://drobilla.net/software/patchage.html
The vanilla start up zynthian settings in this sort of world for starting up is probably everything in dummies with hdmi screen selected.

A Zynthian kit itself wont start if it can’t detect the audio device selected.

[xanderz]

Yes, you are indeed correct. I just quickly found out after doing a bit of google search
I can now access the webconf.
Can’t see any MIDI log though. The midi keyboard is listed in aconnect and I also used it by playing with fluidsynth.
I can see the zynthian splashscreen for a few seconds, and then the error splashscreen.
Again, is there any log file that zynthian outputs when launching? Maybe that gives me a clue.
Edit: Will change the audio to dummy, just in case
Edit2: No, it did not help.

[xanderz]

I just found out on the forum I can get some logs using journalctl.
Here is mine:
