Hey, folks!  
I use Processing with _sound_ library.  
The sound is heavily chopped – as I make dramatic LFO treatments – with the native _Pulseaudio_ server, so I try to use _Jackd_ to see if it is better…  
But I have no sound as I start _Jackd…_  
How to force Processing to use _Jackd?_

You can potentially run jackd with the pulseaudio sink, but I’m sceptical that will improve matters much. I’m not sure the Processing Sound library has a jackd backend? You could look at using Beads instead, which does although I don’t know how much development has been done in recent times.

You could also try using [PraxisLIVE](https://www.praxislive.org) which has its own audio library, Pipes, that will be released separately soon and supports this. I wrote the Java binding for jackd that is also used in Beads and other libraries originally for PraxisLIVE.

I do, but it doesn’t work for Processing. It works for Spotify, for example.

Thanks for the tip, I will try this! 🙂

> PraxisLIVE

Looks powerful! Thanks! 🙂

As I try to launch PraxisLIVE, I have this error message in terminal: _Cannot find java. Please use the --jdkhome switch._

What am I supposed to do?

Do you have, by any chance, a tutorial for Beads? All the links I found are dead… 😑

Was trying to find you a link to that that was still alive! Glad you found one.

With PraxisLIVE I assume you didn’t install via .deb? You need OpenJDK 8 installed. Or an OpenJDK 11 from anywhere but Ubuntu - Processing libs will crash the distro JDK 11.

I installed the .deb package, yes. As I can’t find a package in the official repository…

It works! 🙂  
Now, I’ve got to learn! 😃

> Processing

I tried _minim_ library: it works _jacked and smooth…_ The problem was the _sound_ library… I wonder why this is the official documented library of Processing? 🤔
