Johan,
Thanks for your continued thoughts on this.
Now that I've broken my Suse 10.1 boot (tried a kernel update - no good) -- I have an option of installing any one of the music distros, eg Studio64 (I haev a pentium D proessor) -- or others like gentoo you have mentioned. But Gentoo's installer doesn't recognise my SATA drives.
I'm writing to ask about Studio64 and the other distros relative to what you have said and considering my needs: I am not a musician, although I'd like to keep music generation, recording and mastering in mind -- rather I intend to use Linux as a digital solution in prosound and high-end home hi-fi applications, replacing commercial product$ with better and more flexible software.
The Studio64 "readme" warns that upon installation, the existing partitions may get over-written. Most of these distros warn about that -- I've got my XP production OS on my first SATA drive, and when I had Suse
10.1 working it installed flawlessly on my second (fresh) SATA drive dual bootable vis Grub.
From your experience, in terms of installation robustness and maturity, would you pick one or the other of these distros over the other?
Will Studio 64's install overwrite my partitions or is this just a warning?
Are any of these distros any better with managing and processing "live" sound (not a Live CD -- but an Installed Linux) ? EG, I want to signal-process live audio as in live concerts as well as use something like bruteFIR for home-hifi and home theater (eg to implement digital crossovers, filters, acoustic analysis, etc). Most of the folks I've discussed this with use Linux audio tools for creating/modifying/mastering studio music not "live" sound.
Thank you again,
Ronan

Using Gentoo with an DIGI5296 and ADI-8 AE. The DIGI96/8 is in another pc at
the moment. No problems unless running "emerge --rsync" while recording.

You can make the analog x-over as good as you want but you will never be able
to correct for phase and delay. A digital x-over an do this when you
implement a filter followed by a phase corrector. But before this becomes
something that you can actually hear you have to spend far more time and
money on your room than any normal person does. If you have the luxury of a
separate acousticaly optimised listening room it starts to makes sense.

I bought the RME for the same reasons as you (x-over, phase and delay
correction) but decided that my time _is_ worth something to me. So I dropped
it. The advantage of the RME cards is that you have a lot of IO on a single
card, and that you can add cards without problems later.

In a way they are external AD/DA, only they sit inside our pc. I would not go
for the RME internal IO cards as they will take a lot of space in the pc, and
I would prefer the pc away from the audio and go digital to the setup.
Perfect situation for RME gear. Any AD/DA convertor that has ADAT interface
is usable. I use both a RME ADI and a Fostex VC-8. It will cost, but what you
want will cost whatever way you build it.

The RME is digital, so it could go to DC. But the DA convertors will be your
limit. I don't see what usefull info there is at 5 Hz, but that is your
problem I guess.
