Click Sampler, then click the Virtual Memory tab.Choose Logic Pro > Settings, then select Audio.You can adjust Virtual Memory settings for the Sampler to optimize its performance: This option is only available in Logic Pro on Intel-based Mac computers. If you are using ReWire, set this option to Playback Mode. ReWire Behavior: If you aren't using ReWire, then set this option to Off.Learn more about how to use the Multithreading setting to optimize performance.


Increasing the I/O buffer size reduces the load on the CPU of your Mac. However, larger I/O buffer sizes increase latency when recording. The I/O buffers temporarily store audio data before sending it to other destinations on your Mac. I/O Buffer Size: Increase the I/O buffer size, up to a maximum of 256 samples.Learn more about the Processing Threads setting in Logic Pro and how to adjust the number of cores Logic Pro usesĬhoose Logic Pro > Settings (or Preferences) > Audio, click Devices, then adjust the following settings: You can use this information to make adjustments to your project or your system configuration.

System overload alerts can appear when any of these meters peak. When a meter is full, the CPU or the disk has reached the limit of its processing capability. Watch the meters as the project plays back, noting when the meters are full. On Intel-based Mac computers with processors that support Hyper-Threading, two meters are shown for each core.ĭrive I/O: Shows the amount of disk bandwidth used by Logic Pro. Processing Threads: Shows the amount of CPU and RAM processing power Logic Pro is using on the available cores in your Mac. The Performance Meter has two sets of meters: Double-click the CPU meter to open it in a new, expanded window. The Performance Meter appears on the right side of the LCD.Select Performance Meter (CPU/HD), then click OK.Choose Custom from the pop-up menu in the LCD section.Choose View > Customize Control Bar and Display.Choose any other additional options to streamline your workflow. Choose Logic Pro > Settings (or Preferences) > Advanced Tools, then select Show Advanced Tools.Use the meters in the Logic Pro Performance Meter to monitor system performance while working on a project.
