Yes, this is a real problem. Emscripten is universal yet no threads, performs best on Firefox, and will probably never be as fast as native. PNaCl is faster, has threads but is only running in Chromium. I feel at this point Emscripten is the very flawed best option, if however PNaCl received wider support then it would be a no brainer. -- Edward Costello On Tuesday 5 November 2013 at 14:06, Michael Gogins wrote: > There appear to be some differences with respect to threading.

It something a lot closer to a "universal" Csound application. And it would be easy to do user-defined widgets.
