Improvements to existing code

[NexxuSix]

Hi all,
There is a powerful software synthesizer available today, but it lacks
a few key features. It's been awhile since I've coded, but was wonder
if anybody would be interested in a collaboration on this project?

http://sourceforge.net/projects/zynaddsubfx

One of the main things this synth needs is a way to accept Program
Changes within a bank. There are some revisions initially set up in
the software, but no routines have been written to handle the request.

Snippet from ZynAddSubFX/src/Seq/MidiFile.C:

case 0xc0 ... 0xcf://program change - ignored
skipnbytes(1);
break;

I understand some coding, but I'm a little rusty. Any thoughts on
this?

It is not valid C++, if that's what you wanted to ask.

Well, I don't know if this makes a difference, but this is the source
code that is written with g++ for Linux. Source code should be source
code, no matter what the compiler is, I suppose. What I was hoping was
to soo if anybodt might be interested in helping co-author a routine
for ZynAddSubFX so that it can change programs within a bank. Would
anybody be interested in partnering with me on this project?

Of course it does. Most likely whoever wrote it relied on certain C++
*extensions* in g++ (and plenty of those there are, I might add).

Source code should be source
code, no matter what the compiler is, I suppose.

You're absolutely right. It *should*.

I don't know. I am not, though.

Well, I don't know if this makes a difference, but this is the source
code that is written with g++ for Linux. Source code should be source
code, no matter what the compiler is, I suppose.

Many compilers provide various extensions to the language. These
extensions are non-standard and off-topic here. The case range you show
in the original is one such extension.

I believe g++ provides compiler flags to force it into a conforming
mode, which would disallow or warn such extensions.

GCC has an extension that does case ranges. And yes, it bit me once!

OP: Invoke g++ with -ansi -pedantic, and you should get an error out of it.
(assuming you use GCC)

case 0xc0:
case 0xc1:
// .....
case 0xce:
case 0xcf: { /* body here */ skipnbytes(1); break; }

It depends. C++ source code should be C++ source code, no
matter what the compiler is. But as Victor pointed out, the
above is not C++. When g++ is invoked as a C++ compiler ("g++
-std=c++98 -pedantic"), it doesn't compile with g++. (Like most
compilers, when invoked without special options, g++ compiles a
language of its own, somewhat similar to C++, but not exactly
the same language.)

Ahh... so, in other words, g++ will compile the c++ to a linux
derivitive. I think I'm starting to understand all of this. Well...
the other thing (and to update this thread) is, that I've asked Paul
Nasca to consider updating his code, but so far, nothing. And, I don't
think anybody out on Google Summer of Code has taken consideration as
well. So I'm told that because this Synth is a real time synth, it
might not be possible at all, without stopping the sound first to
change a patch. Well, it would be nice if this was possible, because
ZynAddSubFX has a lot of potential.... and it's a very powerful synth.
I could only hope that Paul Nasca would consider updating the code...
but it seems unlikely... hence the reason I am "here" asking for help.
