Re: Memory Nightmare
Oct 10th, 2009, 06:21
When I tweaked the plist file for Logic Pro 8.0.2 and changed the way Logic Pro treats virtual memory with Leopard and Snow Leopard the result was nothing changed? At the Apple Store me and the One To One trainer tried this tweak with Logic Pro 9.0.2 and nothing changed. Logic Pro 9.0.2 requires a major rewrite since it still is 32 bit has a 32 bit audio engine foundation before it will ever become fully compatible with 64 bit and have 64 bit memory addressing. I still deal with this memory nightmare. Now, by using Presonus Studio One Pro which works and sounds fantastic right now with its 64 Bit double precision audio engine as its foundation on Leopard or Snow Leopard and the proactive support and community of Presonus Studio One Pro now and into the future Apple must convince me that they adopted a proactive approach for me to even be on the fence or consider adding six hundred dollars for retail or even three hundred dollars to get an update to Logic Pro that will be 64 bit.
FYI:
WARNING!!
proceed at your own risk!
FIRST MAKE A COPY OF YOUR PLIST FILE SO IF THINGS GO TITS UP YOU CAN GO BACK TO WHAT YOU HAD BEFORE!!
- Open the ~/Library/Preferences/com.apple.logic.pro.plist file in the property list editor.
- In there create a dictionary item named EXSVMManager.
- In this dictionary create two sub items of type number named VMSegSize and LRUSize.
- Set VMSegSize to 2048 and LRUSize to 64. These values appear to be default in Logic.
- Try setting VMSegSize to 1024 _or_ LRUSize to 32 and check if:
a) you can add 0.2 GB more 3rd party stuff and
b) EXS playback is still stable.
If yes, you might change both values to the smaller number, resulting in 128 MB instead of 512 MB window size.
