Hi there, and also hi @neilcsmith 🙂

I would like to use Praxis live to easily switch between processing sketches during a live performance (using midi controller)

I installed it and tried some stuff, but it’s still unclear for me how to do import your sketches and make them run in Praxis.

Any tutorial or guide that I can use to get started on this?

Thx a lot 🙂

Hi @squirelo 😄 Happy to answer questions on here, although we also have our own mailing list and chat - you can find them at [Community](https://www.praxislive.org/community/)

The important thing to note is that you’re not _really_ mixing sketches - there is still only one PApplet (per graph at least). There are two base components that act like sketches and wrap a PGraphics - either P2D or P3D. You need to add one of these components to your graph - `video:gl:p2d` or `video:gl:p3d`. The other thing to note is that programming is in Java without Processing language changes.

There’s an old blog post on converting sketches - I’m working on an updated post at the moment - [Transform a Processing sketch into a Praxis LIVE component | Praxis LIVE](https://praxisintermedia.wordpress.com/2015/04/01/transform-a-processing-sketch-into-a-praxis-live-component/)

Also, open up the examples and right-click on any node and select `Edit Code` to see how existing nodes are built. Code will update immediately every time you save - fully supports live-coding.

Video of me talking and demoing it (keynote at a Polish Java conference last year) might also be useful - [https://youtu.be/3cQ-8wZwsmY](https://youtu.be/3cQ-8wZwsmY)

Hope that helps! Ask if you need more. 😄

So, how did you get on? Any problems, missing info / features for what you want to do?
