![]() ![]() ![]() I'm currently running 10.5.2, have installed all relevant updates including the latest Pro Kit update and other "Pro Application" updates. ![]() All audio is recorded to/streamed from an external LaCie 320gig drive connected via Firewire 800. I stream BFD samples from an external Western Digital 250 gig drive connected via Firewire 400. Virtual Memory settings are global-they affect all instances of the Sampler in all projects.I'm running Logic 8.0.1 on a new 20" iMac, 2.4GHz Core 2 Duo, 4 gigs RAM. If your projects include a lot of audio tracks, select Average or Extensive. Host Disk Activity pop-up menu: If your projects include very few audio tracks, select Less.You can choose between Small, Medium, and Large buffer sizes. Buffer Range pop-up menu: This setting determines the size of the buffer used for processing audio samples.If the alerts coincide with peaks in the Drive I/O meter, deselect it. When you turn on Sampler virtual memory, only the initial attacks of audio samples are loaded into the computer RAM the rest of the sample is streamed in real-time from the hard drive. Active: If most of your system overload alerts coincide with peaks in the Processing Threads meters, select this option.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. Multithreading: Multithreading affects how Logic distributes the DSP resources of your Mac.As with the I/O buffers, higher settings increase latency. Process Buffer Range: Set this option to Large.You can then set the I/O buffer size to 256 samples and leave it there for both recording and mixing. Choose Logic Pro > Settings (or Preferences) > Audio > General, and deselect Software Monitoring. If you're recording audio and not software instruments, you can monitor your audio directly from the source. To avoid latency and system overload alerts, decrease the I/O buffer size when recording, then increase it when mixing. 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. ![]()
