Both hetero/adsyn, and the Loris system in Csound 5, can do this. Loris is more powerful but takes more learning. I think some of Victor Lazzarini's opcodes can do this as well.

BTW, i can't find the ATS opcodes in the manual at csounds.com. 

originally, ATS included functions to get amplitude and frequency of each
partial, which i think might be of interest to the OP.

Thanks,

I am going to look at the ats opcodes today. I remember that I tried 
once some time ago and didn't get any sound out of it (there weren't 
any error messages either). I will have a go again today and let you 
know the result.

thanks david for the links, i'll bookmark them for future reference.

my point was, however, that the ATS opcodes are not included in the
"official" csound manual as can be downloaded from csounds.com (i haven't
built the manual from cvs in a while). any plans to include them in the
near future?

best,

Hello all

I have the latest (5.02) Csound version installed on my Windows XP SP2 
machine.
I am trying lines like this:

csound -s -oComposition.wav -b4096 -B16384 -m135 composition.csd

...which actually renders the Composition.wav file on my disk with 
perfect quality.


Then, i try this line:

csound -s -odac -b4096 -B16384 -m135 composition.csd

... and the piece starts playing, i listen to some notes but later on i 
start getting severe pauses and cracks and all sorts of noises.

My audio card is a M-Audio Firewire 410. As you probably know, it 
supports ASIO and it shouldn't have no problems of this sort, but how do 
i tell CSound about it?

Please assist

Giant buffer sizes! You probably don't need them that big. In fact
with ASIO they can be very small.

In order to use ASIO you'll have to pass the device number for
your driver. Try this

csound -odac99 composition.csd

This will fail, but will give you a list of output devices. Say your ASIO
device is 5, then you can run

csound -odac5 composition.csd

I'd say you should be able to run it with -B512 and -b128 or therabouts.
