New Engine “Jalv”: LV2 plugins as standalone layers

Great news, @zynthianers!

I’ve been working in a new engine that allows to launch LV2-plugins as standalone layers. For doing that, i’ve used (and extended!) Jalv, from David Robillard, one of the creators of LV2 plugin specification. In his words:

“Jalv is a simple but fully featured LV2 host for Jack. It runs LV2 plugins and exposes their ports as Jack ports, essentially making any LV2 plugin function as a Jack application.”

You could think …  “OK, but we already have MOD-UI that allows to load any LV2 plugin and combine with other plugins in any way we want …”

Yes, you are right, MOD-UI is fantastic, really! But is not a 100% zynthianic animal and some functionality is missing in the MOD-UI layer (and it’s not easy to implement!). In fact, only one MOD-UI layer is allowed in Zynthian, and no MIDI channel assignment is possible, nor cloning or transposing. You have to hardcode all this behaviour in your pedalboard using the MOD-UI web interface. Not a big problem …

But sometimes you only want to have Dexed, Noizemak3r, MDA ePiano or any other LV2-plugin working as “normal engine” in a layer, that can be transposed, cloned or assigned to the MIDI channel you want. And this is what Jalv engine allows. And it’s a small-but-huge step for Zynthian 😉

What is Zynthian?

IMPORTANT: Comments are closed in this post, please, use the forum.

Zynthian is an Open Synth Platform based in Raspberry Pi, some Open Software Synthesizers and more.

I’m trying to integrate all the parts in a realiable case with a nice and ergonomic User Interface, so everybody can enjoy this wonderful synthesizers in any place without having to install or configure anything.


When it’s finished, i would like to make it available for everybody, as a toolkit or as a finished product, so you can use it for Live Playing, Music Production or any kind of experimentation.

Of course, all the specifications will be freely available, so you can build your own device if you prefer 😉
