MIR Pro will benefit both from more CPU-power as well as from fast RAM. Updating to the fastest processor you can achieve will give you better overall performance.  Assuming that your system is capable of hosting it, updating your RAM to the 1600 MHz variety with four (I think) memory channels will help the actual convolution processes, too.

Be aware that MIR Pro's GUI relies a lot on proper OpenGL-implementation of the video card. We recommend ATI cards (but I have good results with a Nvidia GeForce GT 640 on my own system). In any case - we have seen systems which had troubles with MIR Pro due to video card issues.

It's hard to say whether you're better off with a second machine or not. It depends a lot on your habits, your needs and of course your expectations. Personally I like to have everything on one machine, but people who use lots of virtual instruments usually prefer to have slave machines connected via LAN.

HTH,

For a large orchestra a double Xeon is mandatory

 Sorry Cyril,  completely untrue and wrong.

I run very large orchestral arrangements,  no Xeon or SSD here - just a well spec'd  i7 with adequate RAM and hard drives (6TB of Cavier Black's),  though a Master / Slave set up is the best way forward (via VE Pro), leaving the master computer to run the DAW and the Slave to deal with sample streaming.

I am not wrong I did not say " using slaves" ! 

Also it depends if you play in stereo, 5.1 or 7.1 

If you have slaves a double Xeon is not mandatory for your master computer playing your DAW, but may be needed for the slave, all that depends how many instruments and articulations you are loading, and how fast is the piece you are playing and what output format you are playing (5.1, 7.1 ???)

Well, that's a question of how you define "large". 😊

For comparison, I just made a quick'n'dirty test on my own system (Intel Core i7-3930K CPU @ 3.2 GHz with 32 GB of RAM (1600), Windows 7 Pro 64), using a RME HDSPe audio card. An ASIO latency of 1024 samples @ 44.1 khz  with MIR Pro's latency set to 2048 allows for 116 glitch-free simultaneous signal sources in MIR Pro (set to stereo) on this machine:

... assuming that not all instruments will play all the time, it could very well be that in Real Life this number can be exceeded considerably due to MIR Pro's option to switch off any unused convolution processes (in its Preferences).

Kind regards,

Hi Dietz

Interesting, and if put this in 7.1, how does your Intel Core i7-3930K CPU @ 3.2 GHz with 32 GB of RAM reacts ?

 Who ever needs 7.1?

If you took a poll of MIR users, I would reckon that 95% (if not more) of all useage is simply stereo.

A few will use 5.1 when aiming for film soundtracks on DVD, but even then for films on DVD the music is still at the front, music is simply not routed generally to the surround channels, and if you wanted that ultimate MIR functionality of rear surround ambience - what is 7.1 going to offer that 5.1 doesn't?

All the test I have made are in 5.1 and in 7.1. It is a good test to do the same with Dietz computer this to see how his computer reacting

Hi Dietz,

Did you manage to test your song in 5.1 ?

Cyril

No, not yet.
