A better indicator is what most users care about: computationally-intensive tasks like running effects and virtual instruments-especially since some of Logic’s plug-ins are voracious in their appetite for CPU cycles.Īpple’s internal tests rely on a project that stacks instrument and effects plug-ins, to determine the maximum number of plug-ins that can run simultaneously. You could count the number of tracks you can simultaneously play or record, but that’s primarily a function of hard disk performance, not processor speed what’s more, many laptop users record to fast external FireWire or USB 2.0 hard drives rather than the slower internal drive. The question, then, is how exactly to quantify real-time music and audio performance. So would-be upgraders would be very interested to see how Logic 7.2 performs natively on a MacBook Pro. Users can freeze tracks to conserve resources on these machines, but that adds inconvenient additional steps to a workflow and limits live performance options. A PowerBook G4 can perform most basic music and audio tasks, but it often struggles to keep up with more ambitious projects. Then again, running high-end audio programs on G4-powered laptops can be limiting compared to desktops. If you try to run a multi-track audio project under Rosetta, you’ll find degraded processor performance that can result in garbled audio on larger projects. Just the addition of Universal compatibility is good news for Logic users earlier versions of the program wouldn’t run on an Intel-based Mac.
