Display audio overload logic 95/29/2023 ![]() In this example we can see activity on two cores. The channel strip for Output 1-2 has a large number of plug-ins. In the example below, there is a single Software Instrument channel strip with plug-ins routed directly to Output 1-2. If you find that a single core has much higher activity, use these strategies to redistribute the load. This is especially true if you are working at higher sample rates (88.2 kHz+). If you are using many processor-intensive plug-ins on a single channel strip, the core running it may show heavier activity. Each channel strip-and all plug-ins it contains-will be processed by one core. The same concept applies to channel strips as well. This will bring up a floating window, showing meters for individual activity within each core. To monitor Logic as it uses the cores on your system, double-click the CPU meter in the Transport area. This is the main reason that you may get “Core Audio Overload” warning messages even though some of the cores on your system may not show significant activity. If one thread is very processor-intensive, the core running that thread may show much more activity than the cores running less demanding tasks. This is one reason that you may sometimes see uneven load distributions across the available cores on your computer. While it’s not possible to split a single thread across multiple cores, a single core may run multiple threads at the same time. Logic breaks tasks down into threads that can be assigned to a single core for execution. Here is a quick down and dirty guide on how to make that happen. Logic does have the potential to to use all of these cores in a balanced fashion so you can optimize your workflow. Each of these regions can run their own set of computations, so they work effectively as two processors. While a dual core processor, like the Intel Core 2 Duo, will be one “unit” on the motherboard, it can separate computational tasks in two regions. A “core” can be considered to be an individual CPU, although it may not be one physical component of a computer. Pretty much every Mac developed since the jump to Intel processors has at least dual core capability, if not more, especially looking at the Mac Pro towers with 8 cores.
