I have a PB 12" 867mhz 640 MB of ram. Sometimes I use Garageband with a midi keyboard to just for midi playback. The piano and guitar sounds on Garageband are the best anywhere. I have Menumeters installed to see how much CPU garageband uses when Garageband is generating notes.
Everytime I played my CPU would go up to 80% or so. Geee I thought, that's a lot, does this piano sound really need all that CPU? Now my PB fan is gonna turn on faster than an it should (thanks again Apple

) So I did something really simple. I
minimized the Garageband window, changed to the Finder or something else, and viola, the CPU use during playback of a piano was down to 10% or so! Woohoo, now I can play the piano on Garageband all day without hearing that damn PB fan come on. Sorry Apple, your stupid fan coming on at 52 C won't bother me now. Screw OS 10.3.2
