    Hi Bjarne

    My statement related specifically to DG's comment about latency when working with live players, not when recording MIDI.   If you're working with live musicians and have your host running on a separate system, then as long as the musicians are monitoring themselves 'direct' or via a low latency host buffer setting, MIR latency will not be an issue.  In fact DG intends to run everything on one system, in which case it  clearly IS an issue, because MIR and the host would share the same buffer settings.

    I'll have to check into the bypass function, I wasn't aware of it, but have not been using MIR for the last few days.   When I ran some stress tests I found 512 samples (sorry, I keep quoting buffers in ms, brain not working) not  to be a problem, and that involved MOL, and it also invovled audio being routed back to Logic on a separate machine and then from Logic onto another separate machine running ProTools HD via lightpipe.  1024 could become probelmatic, no doubt.

    I would have thought that on a well specified i7 machine you would get very good performance at 256 samples, indeed it may deliver close to the Xeon spec I use.  The only reason I ended up with a Xeon machine is because of the price of 4GB Ram modules for the i7 config, because I wanted the system to have 24GB.  When I compared specs, I could get the dual Xeon system for the same price as a 24GB i7 rig because of the savings on Ram cost.

    Cheers

    Hi Jules - get it now [:)]

     - thx for your input, much appreciated.

    By the way I do think that your dual XEON W5580 setup is significantly more powerfull than the i7 platform. At least when it comes to raw computing power in the form of integer and floting point operations.

    Eh.. I don't mean to be rude to the guy at the start of this thread... But the guy recommending that you buy a good graphics card for a pro audio rig seriously doesn't know what he's talking about. But the cheapest graphics card you can, it will make zero difference to your audio performance. (GUIs have nothing to do with it, any graphics card can pump out a 2d GUI).

    Sorry, that's not true. We have made bad experiences when the graphic card doesn't adhere to some minimal standards.

    ... but of course the requirements are no the same as for full-fledged PC-games! 8-)

    harmish, it appears you _are_ rude ... though i don't know who *the guy* is i can assure you directX10, openGL 2.1 _is_ a system requirement - we had a hard time to get a slightly older directX9 card to work properly ... read through the posts (especially mine) and you will understand ... would you really like to throw your performance resources on the grafic?

    the 5520: we currently have one for testing, 24 GB RAM, overclocked to 2.9 GHz, not yet finetuned ... very impressive ... seems to be a tick less performant than the 5580 (3.2 GHz)

     personally i'm still not sure what the most important part is - CPU speed, memory speed, number of calculation units, level2/level3 cache ... the amount of possible testing scenarios is pretty huge ... we will have to find out.

    Hi Christian

    I suppose the memory bandwidth is increased also when overclocking the 5520 ?

    I've noticed that the X and W types have 6.4Gb memory bus, while the E types "only" have 5.8Gb

    Again, the graphics card shouldn't matter. I mean, I don't have MIR software but as far as I understand it's a simple 2d interface made of images and text, right? So unless it's programmed horrendously badly, a cheap graphics card should have no problem chewing through that interface in milliseconds.

    Hamish - the easiest way to get some first-hand experience would be to download the demo version of Vienna MIR and try. Christian (cm) has already pointed out the needs of its GUI.

    It seems that you don't own any VIs by now, but you could use its graphical features anyway.

    Well I don't mean to tell you that you're wrong. Obviously if you're the programmer you know best. It's just surprising to me, I've only ever experienced 3D applications requiring any sort of decent graphics card.
