- 128 megs is recommended for 001. 192 megs if you plan to use other audio or MIDI applications while using 001.- To adjust the memory sizes for Pro Tools LE and DAE find each application. Highlight the application and select Get Info from the File menu or hit command I. Select Memory from the Show pop up in the info dialog. Increase only the Preferred sizes, leave the Minimums at default values. For Pro Tools LE, set the Preferred size between 32000K and 50000K to start. For DAE, between 31000K and 50000K. Sizes will depend on how much system memory is available on the system as well as the size of your session and how many plug-ins you're running. - Sizes can not be changed while applications are running. Check the About This Computer dialog under the Apple menu (when you are at the finder level) to make sure that you have at least 10 or more megs available once Pro Tools LE has launched. This is to ensure that your system has enough memory once all of the settings have been adjusted.
