Macbook - Logic Studio stress test.

Buzz It Share
In my previous post about using your Macbook as a mobile studio of sorts I stated:
Most of you will be curious to know how many effects you can cram into a project but honestly, it depends, if you want to have 32 tracks with a Space Designer effect on each I'm sure some coughing will begin...
So I decided to conduct a little "stress test" just to see if my own claim was true, well...
Lo and behold, the little Macbook performed very well and it did not even cough, of course the CPU meter went sky high, but the system's performance didn't seem affected.

Here, I list the conditions for the stress test:

1. The computer:
As you can see, I don't have:

a. The latest processor
b. The latest OS X (Leopard), I use Tiger, still
c. The maximum RAM, just 1 Gb.

2. The Logic Pro project:

a. 32 stereo audio tracks
b. 32 instances of the sample: "12 Bar Blues Bass" running on a 4-bar cycle
c. 32 instances of Space Designer - a CPU-intensive convolution reverb effect - on each track

Here's a little video of it, you have to take into account that the software used to capture video from the screen was also running on the same computer and it also is CPU intensive, it was capturing video at 30 fps.

Also if you see at time 00:52 I'm pointing to the battery indicator to show that the Mac was running on battery (usually processors run slower when your computer is not plugged).
This seems to indicate that if my older Macbook can take this kind of "CPU abuse" a similar system with the latest specs (and more RAM) should perform better.

You might be someone who plans to record an entire band with at least 8 mics for the drums alone or a church choir or a school band performance you should normally have no problem using a Macbook.

  2. Thanks for this great post. I'm now sold on an aluminium macbook 2GHz and a Line 6 POD X3Live and midi keyboard as a simple home-studio. Thanks for helping me figure out a workable solution on a limited budget.

  3. i have the same Macbook, but using Leopard and with 1gb more RAM, what do your system preferences look like/what soundcard do you use? as my computer can't even take about 8 MIDI tracks without having an overload error!

    You have to optimize Logic Studio in order to get the most out of it. I would do some reading and researching to make sure your settings are correct.
