It is far from perfect, and I am still working on it (generation of SVG being not my main priority here), but it should work well enough for many usecases. Besides, I'd be super happy to get some people testing it, feedback, and help with finding and fixing bugs...
@Jonathan : Great work! Are you aware of WebPd (
https://github.com/sebpiq/WebPd) ? I am currently doing a lot of work on it, to release a full-web audio API version soon (in branch waa). It would be great to have a GUI that I could hook-up to it. I was actually planning to use this :
https://github.com/the-grid/the-graph which is a generic data flow UI library for the web. It is so well done, works great on touch interface, so I thought why the heck reinventing the wheel. Unfortunately I haven't had time so far to get my hands into this. What are your plans for this node-webkit port?
