Major System overload issues


Recommended Posts

I have been working on a new song since upgrading to Yosemite OS. There are a small handful of audio tracks and a couple of EX24 instruments and then a Contact Multi instrument running 15 tracks of software orchestral instruments (mixture of Kirk Hunter strings and Contact factory wind). My song is constantly crashing and the CPU and I/O are pushing to maximum.


Here's the funny thing - even when I mute ALL the tracks the audio is still running pretty high even though I hear nothing. I concede my iMac is a little outdated (2.8 GHz Intel Core 2 Duo, 4 GB 667 MHz DDR2 SDRAM, ATI Radeon HD 2600 Pro 256 MB using built in sound running audio at 48,000 kHz with 256 buffer) but a) the problem seems intermittent [i.e. one time I can run and edit no problem, another time it just keeps crashing even after a clean restart] and b) if I have to accept that my machine can't handle all of this anymore is there a way I can "block" tracks i don't need to run to free up processing power whilst I work on the orchestration?


I've already frozen the audio tracks and NOT the software instrument tracks (as advised on another page).

Ive had the same problem with logic.

With just logic on my cpu uses 15% and ram uses 2,4gb (max4gb). When i start my song playing in logic the cpu changes allot.

Cpu is going to 100% but ram remains the same. When this happens logic stops playing my song and there is the error message!



What you want is that logic doesnt hit the 101% cpu usage to trigger the overload.



1.Get the app: App Tamer.

2. Search for logic pro in the list for cpu usage.

3. Right click on logic and select that slow program down when it uses above 50% cpu.


Before i already got these messages when i play the first 2 seconds of a song. Now i never get a message and logic is running great!

Logic pro is like a dog without a leash, it wil run away with your cpu so get that leash hold it tight and give it some discipline. :lol:


This is my fix for the problem, hope it works for you
