use fout instead of soundout.

hummmm.... can you add some of these examples to the manual - and a  
monitor example.

showing how to do this is very important and useful - and not exactly  
intuitive or clear - yet.

wishing you all the best.

Hello all

Since i am trying to migrate from Windows to Linux, i have tried several 
hardware combinations in order to build a good and stable system - also, 
one that will be able to handle my csound attempts.

I don't have enough csound compositions of my own, so every time i set 
up a system like that,i download Steven Yi's csd files (from his site) 
and test my csound installations by running them and hearing the results.

Why? Because some of them seem to be more demanding in terms of 
processing power (for realtime rendering to dac), so i am thinking that 
if "distant stars" renders fine, then the system is adequate for my 
current needs.

This afternoon, i thought that some sort of official benchmarking should 
exist, so that one could perform a series of tests and determine the 
adequacy of any given system. This may not be very important to Windows 
users (with all the asio stuff), but in the world of Linux, where low 
latency audio (or firewire audio, for that matter) is a bit elusive, one 
needs a system for evaluating such things.

Any thoughts?

Panos,

I think the stock kernel these days is quite good, but you can get the patched
RT kernels off planetccrma, which are nice and reliable. I use my own
kernel builds, but you might not want to do that ;)...

So my suggestion is to start off with the planetccrma distribution, which
is fedora based (I think). I am very happy with fedora, never gave me trouble
(been using it since, I don't know, red hat linux 4?). Other people find
it not as easy as Ubuntu, but I don't like the fact that Ubuntu makes you
download everything you need after you installed (it only comes with
the bare minimum).
