Re: [Csnd-dev] [EXTERNAL] Re: [Csnd-dev] new API

Hi!

One more question:
CsoundQt uses csound_threaded.hpp  to support html files that us Csound.
The files is present in feature/newapi branch but not updated yet.
What are the plans with it? I am not sure, but I think MIchael Gogins wrote
this wrapper?

Thanks!
