I'm currently mixing a piece with 73 stereo tracks of live strings, horns, and woodwinds. I made group tracks for individual section (like V1, V2...etc.), and each group I have inserted MIR Pro. There are clicks and pops when I play back my session that make me unable to proceed the mixing.

My system spec. is i7-3970x with 32GB of ram, everything is SSD. I have both MIR and project running on my C drive. Also, my main sequencer is Cubase 7.5.3 running under Windows 7.

I wanna know is MIR Pro able to used for large project on a single computer, or do I really need a dedicated computer as MIR Pro DSP?

And how do you pro's system setup for using MIR Pro for mixing large projects?

 Hi William,

I use a comparable system for development and audio work. Using MIR Pro as VST plug-in (opposed to its VE Pro-based version), I can easily use 100 and more stereo-instances in Nuendo (which is quite similar to Cubase). Under "laboratory conditions" I can use over 150 instances without CPU overloads.

Some things to consider:

- What's the system's sampling rate? (Higher rates will increase the CPU load.)

- What's the format you're mixing to? (Surround setups will almost triple the load.)

- What's your audio system, and what's its latency set to? (... for mixing, I suggest to switch to 1024 samples at least).

- What's MIR Pro's own latency set to in its Preferences? (... for larger projects, it helps to set the buffer to at least the same value as the system's latency.)

- Have you de-selected Cubase's "ASIO-Guard"-option already? It can wreak havoc on some audio processes, as experience has shown.

- Any "smart" Virus-checkers working in the background ...? 8-)

... if you still can't get to useable results, please get in contact with , including as many details as possible. We'll try to help you to hunt down the bottleneck you're running into.

Kind regards,

Hi Dietz,

Are you recommending to disable ASIO-Guard globally or only on specific plugins in the plugins info page (MIR Pro, VEP, VIP...)?

Hi FredB,

Dietz is on holiday right now. We all disabled the ASIO guard with Cubase, works better in our experience.
