Hello Forum ( log time reader first time poster), I could very much use some help on this subject for a lot of you "veteran" computer guru's /engineers. Here is my problem. I do a lot of jazz recording, trios ,quintets,quartets even big bands. Until recently, I have not been happy with the quality of sound i was getting. I was recording at 48k then i switched to 96k and whoa what a difference in quality, So I started tracking at 96k. I now that 96k sucks up cpu like crazy so I would only track at most 8 tracks all together. I use logic pro9 as my DAW . I have noticed when only working with 2 audio my cpu starts to peak and I get an overload message ( refer to the images below) I don't use many plug-ins maybe 4 or 5 altogether max. Macbook 2.1ghz intel dou core 4gb ram Saffire pro 40/Saffire octopre dynamic mk2 Logic 9.1 My Macbook is pretty solid -Ive got a 2.1 ghz duel core /4gb of ram. It shouldn't be spiking with only 2 tracks!!!. Also, Attached is another project I have recorded at 96k 8 tracks all together may 8 -10 plug-ins altogether. I am only working with audio tracks not any logic midi or sample tracks My question- Although I am working with 96k I am not working with many tracks or plugins at all. However, cpu is getting pounded! If I added 2gb of ram to my mabook, would I be in good shape? or do I need more cores and more ram to fix this problem? I have read a lot of the threads on this subject and these are the steps I have already done[/B ( below)] Is there anything I have not tried that would optimize my cpu performance .Any advise and help on this would be greatly appreciated. In Logic 9 -froze all tracks -set buffer rate to 1024 samples -reduced my undo history to 5 -lock all tracks -process buffer range -set to large On computer- -use and usb 2.0 external hard drive -disable spotlight -format external hd to mac os journal Is there anything I have not tried that would optimize my cpu performance .Any advise and help on this would be greatly appreciated. Here's an update- I went out and bought a brand new Mac Mini 2.5 Intel Core i5 10gb ram 1600Mhz DDR3 running Mavericks. I updated Logic to version 9. 1.8 And I STILL get the cpu spikes I did as if I was on my old computer!!! What is going on? I mean really I have 8 tracks recorded at 96k with maybe 10 plug-ins all together.......I just might have to switch to pro tools 11 The plug-ins I am using are waves plugins v8.
