I've got two Powercore cards and 4 x UAD-1 cards working in a single 13
slot Magma with the POCO's sharing IRQ 18 and the UAD-1's sharing IRQ 17. My
3 x RME cards are in a second Magma all sharing IRQ 19 so pending a serious
torture test to test the PCI bandwidth, it appears that this may play nice.

I'm using an older gigabyte GA-K8NS Ultrra 939 (AGP based board) and the AGP
is on IRQ 16 so since there is no IRQ sharing, unless my PCI bandwidth is
all used up, I'm not expecting any problems.

I'm currently converting everything I'm working on to 88.2KHz. I don't know
if this is going to end up being a waste of time or not, but I figure, since
I made the decision to move to an 88.2 capable system, I need to start using
it. I've spent quite a bit of time and effort getting all my hardware DSP
processors to function at 88.2 and I wanted to try to offload as much CPU
load to outboard hardware and DSP cards as possible. Since my UAD-1
resources will be cut in half, the extra POCO's will be there to pick up the
slack. I've got a couple of 750GB SATA Barracudas to handle the
recording/playback and backup so here goes.

Upsampling existing projects in Cubase is pretty easy to accomplish and
perhaps the OD's and final DSP processing at 88.2 will add a bit of extra
mojo to the mixes..............before they get hosed by the MP3 codec.

Just in case someone wants to go down this road, the compatibile slots in
the Magma are as follows:

1, 5, 7 and 11 share IRQ 17
2 and 6 share IRQ 18
If you are adding a second Magma, use 1, 5, 7 or 11 for any audio cards or
DSP cards. They will all probably populate IRQ 19, or some other compatible
IRQ that doesn't share with the AGP, or the devices in the other Magma. If
you've got two PCI slots that don't share with the AGP or each other this
should work.

OK....I'm off to give this thing a hard test drive. I'll let you know if
anything catches on fire.

FWIW, I don't believe you'll get much benefit from
upconverting a 44.1 song to 88.2 - the plugin's will
process with the higher resolution, but there's
not going to be anything better about the files that were
originally tracked at 44.1, so unless you've got a lot of
overdubs to do on each of those songs, you're probably better
off staying at 44.1 for the rest of the tracking, but then when
you mixdown, go ahead & render to an 88.2k/.24-bit stereo file
for mastering purposes.

OK Neil.

Thanks for the pointers. these higher sample rates are something new to me.
I read an article by a heavy hitter engineer a while back where he said that
he upsamples everything to 88.2 for mixing, just to get some benefit from
the plugin resolutions.

Both POCO's are behaving nicely with the UAD-1's. I'll bet I could even get
another one working. Might be worth a try. The older MK1 cards are dirt
cheap on EBay these days. The higher rates really do suck the resources on
a UAD-1 card....big time. I would venture to say that 88.2 may take a bit
more than twice the bandwidth of 44.1 on these cards. A single La-2A takes
7% or the resources across 4 x cards. that's a pretty hefty chunk 'O DSP.

I just did a little PCI bandwidth torture test at 88.2KHz instantiating 33
DSP (and two of these were UAD-1 Neve 33609's which are the equivalent of
about 5 other processors) based plugins on a 10 track project. UAD-1
resources were at 90% and the resources of the TC cards were at around 85%.
No dropouts or other racket at all with the buffers set to 1024. CPU
cruising along at about 20%, no disk streaming spikes (this is something I
need to test with larger track counts though) and I've got a little bit of
wriggle room on adding more DSP based plugins, depending on what they
are............and I haven't used a single native plugin yet. I'd say that
the system is robust enough to do pretty much any tracking/mixing job that I
might be asked to do here..

I'm going to quit sweating the upgrade situation for another year or so. By
that time, hopefully there will be the possibility of exponentially better
performance at lower latencies. Right now, this system is lookin' good with
DSP horsepower to burn.

Now.......back to the lab.

;o)

Really? I wonder why he just didn't record at that samplerate
to begin with, then? Interesting - well maybe I'm wrong about
the degree of benefit you'll get from upconverting - maybe
it'll be more than I thought. I was just figuring that since
all you'd be doing was converting each sample to two samples, as
opposed to recording twice as many samples per second, you're
certainly not improving the resolution of what's already been
recorded; you're also not changing the high-end content, as
dictated by Nyquist frequency, of what's already been recorded
at 44.1; AND, if there's any FIR filter noise present on the
original 44.1 tracks, you're not eliminating it by upconverting
after they've been recorded. Based on those factors, I figured
it wouldn't make much of a difference except for the plugin's.

Now, in Bob Katz's "Mastering Audio" book, he says that he
upconverts 44.1 & 48k projects to higher samplerates for
mastering for the same reason as your guy mentions - he wants
all the processing, whether it's going through one of his
digital outboard pieces or a simple dither plugin, to be done
at the higher resolutions, so maybe upconverting like you're
indicating gives the same benefits earier in the life cycle of
the recording.

I'll see if I can find the article and post up what he said.

Doesn't working at 88.2 preclude using the UA 33609?

Hi DJ,
Your insane.
So I take it the TC card I sent ya worked. Sure wish it worked on my
machine.

thanks for the info DJ. I wonder if this scenario will work with a UAD-1
