because there is no any big problem with budget, I didn't give any  
information about this. sorry.

well, not all soundcards I know are able to produce 6 independent  
analog sound signals. actually, I wanted to know the hardware that  
people was using rigth now.

It can be a desktop computer. It should be a quite powerful one. I  
give some reasons below.

I believe I just need a PCI soundcard. do you think there are some  
PCI Multichannel cards easier to install than Hammerfall's?

quite complex patches, I said. by the way, implementing all sort of  
synthesis algorithms. for instance, granulation algorithms with a lot  
of granulators changing granulation parameters depending on incoming  
values from an accelerometer that is giving values to the serial  
port. also, multiple fft filtering instances behaving independently,  
and so on... I can't be more precise because I haven't already  
written the patches. I use to write them progresively until I feel  
the machine is reaching some reasonable limit of cpu charge.

I believe there shouldn't  be big problems here. despite of I don't  
have a very big experience in linux -I've just administrated one  
server running linux-, I know quite deeply other operating systems  
belonging to the Unix family.

well, if I ask here, it is because I haven't a lot of time to  
research by myself :(

I think I'll have a lot of questions for you after having made some  
decision, bought a computer and a soundcard and  installed a linux  
distribution ... anyway, I hope when linux and hardware have been  
sucessfully installed, the pd installation is quite straigthforward.  
or not?
