This may be a noob question, but why does my Macbook Pro run Soundtrack Pro so slowly? I have a late 2008 Macbook Pro non-unibody with 2.4 Ghz Intel Dual Core and 4 gb of ram. It runs Final Cut Pro very smoothly. On average I work with around 10 tracks of audio, but even if I have two or three, it still runs slowly. It applies effects and saves my project very slowly. Running 10 tracks in Final Cut Pro also runs smoothly. So, do I need a computer upgrade or is there another solution. Thanks you!
