I have no plan to remove or rewrite this opcode. It should compile and run on any reasonably current version of the GNU Compiler Collection, Intel compiler, or Microsoft compiler. I have not tested it yet, so wait a few days. I will make sure it builds on Linux tonight, and test its functionality.

Both C++ and templates have been used in widgets.cpp, vst4cs, and fluidOpcodes for years. In addition, CsoundVST is written entirely in C++ and makes quite heavy use of templates. I think this proves C++ and templates are OK in Csound. 

In my view, Csound would contain fewer bugs and run slightly faster if it were coded entirely in C++. This view is based on experience and experiments, not opinion. I am prepared to show code samples and experimental results to support this view. I would of course be very interested to review code samples and experimental results that demonstrate the opposite.

I think it should be removed or rewritten in C, or at least no templates
should be used.

John ffitch's and mine apparently not included...

And, as we all know, widgets.cpp was almost as much of a pain
to maintain and make it compile on all platforms as the rest
of the opcodes (less problematic as written in C) combined.
And widgets.cpp still does not work perfectly on all systems.

No wonder I have never been able to compile it. I always get
thousands of error messages, and have given up on ever getting
it work.

I disagree, and the fact that mixer.cpp did not compile is just
another evidence.

This is I think a really good point. I was checking out my friends Nord 
Modular the other day, and thinking that it would be pretty damned cool 
to be able to do the same kind of thing with csound. Make a csound app 
that gets loaded into firmware of a tiny little box with nothing but a 
midi port and a sound port. With microcontrollers and dsp chips getting 
faster and faster, that doesn't seem so far fetched anymore.
