Ok the video that I'm posting is why I love Macs! If you can do this with Windows somebody please let me know and my opinion of Windows will change only slightly though. Now I'm not a DJ but what "eangolden" is showing us could apply to any workstation and it wouldn't matter if your working on video or audio! You would just have to modify the settings to fit your need. What he is showing also would definitely benefit those with less RAM or processing power. The only downside to this feature is it's only available to Leopard users. So let the optimizing begin!
