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
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
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
Hope that helps! Ask if you need more. 
Awesome thx for the fast answer, I’m gonna try this today.
Cheers 
So, how did you get on? Any problems, missing info / features for what you want to do?
