Thinking about this, I think it will be better
to do a separate Intel-only package, built and
tested on a Intel machine. The reason is that
I will need to build and test all Csound dependencies
as well. For instance, I don't know if libsndfile
and portaudio will work straight out of the box
on an Intel Mac. If the configure script sets
everything OK, then it should work. Build UB
versions of all dependencies might quickly become
a nightmare.

I am hoping to get a machine soon. We'll see then.

This is especially true for libsndfile. The libsndfile
configure script does things like detect machine endian-ness
and then compile endian specific code. Obviously this doesn't
work for universal binaries.

I had to rebuild portaudio on the intel (for something else) There's  
a Makefile.darwin.
Came up fine, I've had no problems with it so far. In some other  
builds I've run into edian problems.

Portaudio's simultaneous sine test maxes out at 169 (standard 80% CPU  
load)

MacCsound 1.3 is very stable (no crashes ... yet)

I have quickly glanced at the csound sources for endianess issues and the
two suspects were OOps/pvfileio.c and the code for  soundfont opcodes.
The first one seems OK, as it cleverly checks for endianess, but the
second one might require some work.

Does anyone suspect of any other possible problems? Since file IO is
handled seamlessly by libsndfile (I thank Erik & co every time I have a look
at it for saving us so much grief!), I'd say we would be OK elsewhere.

If the tests are simple, just shoot me a line with directions on what to 
do. If they are more complicated, gimme a week to get up to speed on the 
thing. Great machine for web dev and practicing horn though!

Hi,
The spam filter is getting really aggresive....

I tried it today and it works! Sometimes you look so hard you don't see 
it in front of you....
I just wanted to ask what's the way to change the MIDI interface in 
MacCsound?

Cheers,
Andrés
