Do check the M-Box situation, but my gut instinct is that you are not going to have any luck with it.
I have always used RME and never had a problem. Some of the older audio cards don't have 64bit drivers, but the newer ones do. Make sure that you go for a PCI or PCIe interface. Don't go mucking about with that Firewire cr*p.

yes it will, though we cannot say currently up to how many instruments on stage with which plugins inserted ...
IMO it is not the best idea to buy the slowest processor of the i7 series just for MIR .... if you think the 965/975 is too expensive consider at least the 940, 950
of yourse you can choose a smart for driving in indanapolis or monza, but more efficient would be a porsche ;-)

Simsy - you have to be aware that whatever hardware you buy now: There will _always_ be faster and cheaper stuff, just a few weeks later. 8-/
Of course, if the CPU is a bit stronger, you will be able to use a few instruments more, or have lower latency with the same amount of instruments. But make sure that you components are _all_ in the same league. It doesn't make sense to have a slightly faster CPU when the graphics card is the actual bottleneck, for example.
HTH,
Thanks Dietz,
This is finally what I have settled on
Intel i7-975 3.33 Ghz
Asus Rampage II Extreme Intel X58
Corsair Dominator 12 GB (6x2GB) DDR3 1600Mhz Tri-Channel RAM
Also, a Profire Lightbridge to get the audio back to my DAW machine. Just until MIR Premier is released [;)]
So, before I finally hit the order button. Can I get the OK from you guys?
Simsy, looking into your registered products i'm under the impression you might run short with 12 GB (what would be sufficient for the special edition) - i'd consider to instantly start with 24 GB ...
system: ~ 1GB, IR: ~ 4GB -> ~6 GB left for loading patches .... if that is according to your usual method of arranging its OK though.
sidenote: you also may find needing to spread the sample content across 2 disks

Re: RAM
In a stress test I ran today, I had 50 indivdual VIs playing glitch-free at the same time in stereo, latency set to 1024 samples, CPU @ 80%, with a system comparable to the one you outlined above (12 GB RAM). I used 11.2 GB RAM for this setup, with Nuendo 4 for MIDI output on the same machine.
Taking into account MIR's abilitiy for dynamic processing (only those VI's that really play will use MIR's convolution core and thus tax the CPU), you will most likely run out of RAM before the CPU overloads. :-)
HTH,
Hi CM,
Yeah, on my current VE 3 slave I have a lot more RAM than that. But the i7 motherboards only have 6 DIMM slots and it is very hard to find more than 2GB DIMMS without them being really expensive!!! I might load 12GB in for now and have to reduce my template until 4GB DIMMS come down in price.
Do you know of any relevantly cheap 4GB DIMMS?
Also, Dietz, very interesting with the 50 instruments!!! That is very impressive, is there a dramatic fall in number of VI's when you reduce the latency to 512? Really looking forward to this product by the way!
Can't believe you guys are online on a Saturday night [:D]
Kingston ValueRAM DIMM Kit 12GB PC3-8500U CL7 (DDR3-1066) (KVR1066D3N7K3/12G) 3 x 4 GB is sold heree for about EUR 1.000.-
(note: having 2 modules per channel will drop memory bus frequency down to 1066 anyway)
interestingly the server modules (for XEON 5520 series, ECC) are sold for EUR 200.- per 4 GB module .... strange, isn't it?

This is really useful information Dietz. Certainly I use more Instruments (about 120), but rarely more than 70 playing at the same time. Obviously 1024 latency is useless for programming the MIDI, so how does that work, bearing in mind I'm used to working on my current system at 128? Is there a super-efficient mode for low latency use?

DG, please keep in mind this is on an i7 system and reduction of latency increases CPU load, not necessarily in a linear manner though.
more powerful systems (eg. using 2 x XEON W5580 = 16 virtual cores) will help, but i', not sure if 128 would be even possible ... maybe wait for the 6 core XEONS announced for early 2010
christian
EDIT: i just noticed that obviously it _is_ possible to get down to 128 on a 2 x XEON 5580W machine - this is more than i dared to hope for ...

I fully understand that MIR can't possible work properly at low latency with current computers, but there needs to be a mode where one can at least play the notes in (with various real time controllers) at low latency. I play everything live, and in the case of Woods and Brass, I do all the expression with a BC, which has to work live at low latency. If MIR can't be by-passed when in input mode, then it becomes much less useful.

Hi guys,
Don't know if anyone still remember me.
I've finally settled down for graduate. So finally I can get back to VSL community. Also finally I ordered VI for myself - although only Solo Strings I and Appassionata Strings I. 2500 dollars is a lot of money in China, espeically for a student:)
Looks like you guys are talking about supercomputer now! MIR is definitely a mir-acle:), this will render my research useless:) But I'm glad that such an easy to use environmental reverb exists. Although I don't know if I can buy that after its getting out. But I will buy it immediately if I can.
I'm now using a dual quad Xeon 5410 with 8GB RAM. I have to say that core number is only one question. Applications have to be fully optimized for multi-thread or multi-core in order to make full use of CPU. There are some problem with DAW on windows. I'm using Ableton Live now but I found that Live will drop out even my CPU has only 50% usage. I just hope that MIR is fully opitimized for multicore. cause in my view, multi-IR convolution is kind of parallel work so It is great for multicore.
Also, Core i7's integrated on-chip memory controller and L3 cache design can greatly improve memory performance. So I think that's why VI will run faster on i7. But i still believe memory bandwidth is only one factor on processing power. Processor's raw power will always be the most important factor.
and BTW, there always been supercomputer somewhere. I've seen 256 Xeon CPU server when it's 2002 in my city's electricity control center. Although these machines are for industrial control or more mission critical environment like finacial data center or something like that. My point is that there always are ways to build SMP(Symmetrical Multi-Processors) computers with 64, 128 or more CPU or cores using Server CPU like Xeon. But this always is my fantasy to have such a computer for music production :)
And, I don't think my 8 core Xeon 5410 with 8GB RAM will be enough for MIR and VI....may be
Also, BTW, it's good to be back.
I have the same question about inputting midi while using Mir. All the examples that have been given seem to use really high (1024) latency settings. From a composition/workflow standpoint, how does one input lines at lower latency?

May be we could only use faster computers for MIR. Lower latency means higher computing intensity. So logically only solution should be using faster computers.
I can bare with 256-512 samples ASIO buffer size for composition. But no one is the same I think.

it will not be possible to investigate in detail on the performance of every computer/processor combination, but i'd estimate such a machine can run about 16 instruments placed on a MIR stage .... in any case it is powerfull enough for a lot of VIs ...
welcome back btw, christian
