Re: sdif support
Hi all,
There is a sourceforge project with a c++ sdif file support library.
I am not really convinced that doing this exclusively at the UGen
level is the right approach.
Obviously it is nice to have support at the UGen level, but it will
be easier to adapt to new extensions
by doing file pre-processing in the language and then feeding values
to the server.
So, I would vote for an SDIF file class in the language as well.
