The Zynthian project

Recently I found out that I was not the only one trying to build a synth module out of a Raspberry Pi with ZynAddSubFX. The Zynthian project is trying to achieve the exact same goal and so far it looks very promising. I contacted the project owner to ask if he would be interested in collaborating. I got a reply promptly and we both agreed it would be a good idea to join forces. The Zynthian project has all the things that I still had to set up already in place but I think I can still help out. The Zynthian set-up might benefit from some optimizations like a real-time kernel and things like boot time can be improved. Also I could help out testing, maybe do some packaging. And if there’s a need for things like a repository, web server or other hosting related stuff I could provide those.

I’m very happy with these developments of our projects converging. Check out the Zynthian blog for more information on the current state of the project.

      1. Hey @Georg, the current build system is ZynthianOS and it could create Armbian builds that would support Odroid-C1+. But you will need to help out, I have no way to test them.

    I’m planning to do a similar project on an Orange PI PC (Allwinner H3 SOC), to run Hydrogen drum machine.
    I think that it might be a good idea to build a custom “linux embedded”, special kernel with only needed drivers, bare minimum libraries, etc…
    What do you think about this, would you be interrested in giving me a hand ?

    Regards !

    Hi Jeremy, cool audio projects you are running on the RPI.

    I have a RPI3 where I “almost” have gotten Jack up and running with a USB soundcard. After using qjackctl and tweaking the buffers etc, the latency I get without immediate xruns are in the 10-15ms range when i try to pipe input to output with jack.

    However….., after some minutes the sound becomes very noisy. However there is no crash or overruns at least when I set the soft option to ON.

    I tried your USB 1.1 tweak in boot.txt but then my keyboard attached to the RPI 3 didnt work anymore (LOL).

    The goal is to run with GUI via HDMI, a soundcard taking (mono is ok) sound in and doing some audio effects on the audio, sending it out via the audio out.

    What do I have to do on the rpi3 to get this running?
