Re: csound in OSX...

Hi Simone,

In that case, here's some background information for using on the 
commandline (sorry if some of this is too simple but I'll write to 
assume no knowledge in case others are interested)

1) When you open the terminal app, you'll see a prompt. Most OS's 
preconfigure the prompt to tell you what user you are as well as what 
directory you are currently in.

2) Once you get a commandline version of Csound, unpack the file and put 
it somewhere convenient. To start out, you might want to put it in your 
home directory. If you're user name is simoneg, then your home directory 
on OSX would be /Users/simoneg.

3) When you open the terminal app, you start off in your home directory. 
If you've unpacked csound into that directory, you should be able to run 
it by typing:

./csound

and then press enter. If all goes well, you should see a bunch of 
messages from csound telling you that you didn't give it an orc or sco 
and what the flags for csound are.

4) When you type a command in the prompt, the shell (the environment 
which you are interacting with via the prompt) tries to locate that 
command in the PATH to run it. The PATH is a list of directories that 
the prompt searches for executable programs. Normally, the PATH is 
configured to some default directories. In the users shell configuration 
(the .cshrc file in the users home directory on OSX), you are able to 
add directories to your path with something like:

export PATH = $PATH:/some/other/directory

this is generally complicated for first-time terminal users.

5)Something easier to do might be to see what your path is already set 
to, and see if you can't copy csound into one of those directories. To 
see what your path is, type this on the command line of ther terminal:

echo $PATH

and press enter. It should give you a list of directories, separated by 
colons. Any of those directories can be used to house csound and let you 
run csound without first prepending it with ./

6)Commandline programs generally have the convention:

programName [optional arguments] requiredArguments

where optional and required arguments can sometimes be interspersed 
(depends on the program). If you have an orc and sco to test out, copy 
them into your home directory and if csound is copied there too, open 
the terminal app and try this:

./csound -A -o test.aiff test.orc test.sco

or:

./csound -o dac test.orc test.sco

the first one writes and AIFF file called test.aiff using test.orc and 
test.sco, while the second one outputs in realtime to the soundcard 
using test.orc and test.sco. You can replace test.orc and test.sco with 
test.csd if you have a .csd file.

Well, hope that helps! I'm sure there are tutorials floating around the 
internet for how to use the terminal which can explain these concepts in 
more detail.

Good luck!
steven
