Redistributing CPU Load in Logic Pro 8

To monitor Logic Pro 8 in Mac OS X as it uses the cores on your system, (which could be a 2-, 4-, or 8-core), double-click the CPU meter in the Transport area. A window then opens to display a meter for each core. If you see that a single core has much greater activity, then here is a strategy to redistribute the load: if the left core is handling a software instrument with plug-ins – and this is routed to Output 1-2, which has a large number of plug-ins, as well – you can actually use the routing capabilities in Logic to distribute the load to more cores, without changing the sound. You would route the instrument to the Bus 1 output, then the first four plug-ins would get routed to Aux 1 and the next four to Aux 2. Finally, Aux 1 and 2 would get routed to Out 1-2. Thus, you’d be using four cores rather than two (on a quad-core Mac).
