The majority of the source code is publicly available, though no longer under a traditional open source license. Over time I came to realize I was not really cool with it being used commercially or rebranded without me having some say in that.

The core engine code (pure Java, no UI dependencies) is here: https://github.com/heronarts/LX

The Processing-based UI layer is here: https://github.com/heronarts/P4LX

My future version is moving to a UI based upon LWJGL + bgfx, as the project sort of outgrew Processing as it's become a full application.

This new UI layer is here: https://github.com/mcslee/GLX

I don't publish the code for all the application scaffolding and UI implementation, though everything's designed for extensibility and a sort of plug-in model where having access to that shouldn't be necessary to be able to use and customize the application's behavior.

As referenced in my other comment, this new version should hopefully be available by end of year and will be called Chromatik: https://chromatik.co/ - this will include more documentation! And the goal is for it to be easier to use, no IDE/GitHub required (that will still be available for those who want it), with simpler end-user licensing as found in typical media production software.
