iMac i5, Cubase 7 and CPU usage.

Hi to everyone! First of all, I wanted to say I'm new in this forum but I have long time reading you. I hope my first post is in the right place.

Well, my problem is: As I've been learning how to mix, I use more plugins that increase CPU consume to the point of having a lot of peaks. Since I have kemper, the thing improve but unless I set the buffer to the maximum, I cant mix without cuts and pops. The number of tracks that I use isnt excessive (about 25/30, SD 2.0 with drmagog, waves plugins...). Is this normal? My iMac isnt enough and I need more CPU? Someone in the forum with the same problem or similar equipment?. I'm desperate. Thank you!

Equipment:

Intel Core i5 Quadcore
3,1 GHz
12 GB
Cubase 7 Artist
Apogee Duet 2



P.D.: the computer is recently formatted and I know that have been some problems with Cubase 7 and OSX in reference a CPU usage, but something similar happens with Reaper to me.

Im really sorry for the bump but no one can tell me how far your CPU squeezes when mixing with a same or similar specs? I'm desperate. I do not know if my mac is broken or what...

I could try to compare tomorrow. You have Waves V9 so the plugins are VST3, not VST2? It's a substantial improvement.

I use C7 with Waves Mercury on an 2010 iMac (2.8 ghz quad) w/ 16 Gb of RAM.

Just describe your typical session how many audio + midi tracks, buffer size, which kind of waves plugins etc...not a scientific test but just to see if we're on the same ballpark.

Thank you so much for answering. It is an issue that worries me a lot. Here show two screenshots of Mix Console (I divide it into two to show all tracks). Waves plugins I use are the 9r11 and in this case, the guitars are Kemper Amp Profiler because if using Amp Sims and Lecab directly would have to freeze a lot of tracks. The buffer is at 256 in the photo (I usually mix to 2048 but still the CPU load is high in this case and I want to show you with a "normal" buffer).

As you will see, not use VSTi's except Superior Drummer but I read in forums people using many VSTi's and FX with similar equipment without any problem

Thanks a lot, man!

Np, I can try tomorrow.

However I can tell from the pictures that you're using over 100 plug-ins. Your track count isn't heavy but you do use a lot of plug-ins.

I was not aware that many plugins I used so far... ´:(

Then it´s my high CPU usage normal, right? How many plugins do you usually use for a mix of rock / metal (or whatever)?. Thanx for the help!

You have to determine what processors can be put on a bus, and used by multiple tracks.

To get an overview of the relative performance of different Mac models, checkout this thread, it uses Logic as a stress test.

Newer models are in the more recent threads.

Thank you so much gdoubleyou. All is more clear to me. I think that I demand to my imac more than it can give. Only one more question: I have the possibility to upgrade my i5 3,1 to an i7 3,4 for 400€. In my place, you do that or buy Vienna Enssemble Pro? (I have also a PC with an i7 2,8. Thank you so much everyone, you have me been a great help!!!

P.D.: sorry for my english

For posterity -- this could be a latency problem. increase to 512 or 1024 in settings.

Check ASIO guard as well. For me it´s best when it is activated.

The i7 quad will be more powerful, if you are doing large arrangements VEP5 is the way to go.
