I have a Dual 533mhz G4 with 896mb of RAM runnning OS X 10.2.8 - my question is how well will this machine cope with Garageband and recording multiple tracks? I would typically record at least 4 tracks for a five minute song - drum loops, bass, guitar and vocals with additional tracks for guitar overdubs or different sounds. I would like to be able to apply effects on each track but I'm wondering if this G4 will be able to handle it. I am only intending to use Garageband as a writing tool - no plans on using it for anything other than demos for my bandmates so they can learn the songs I write and get a feel for the vibe of each one. I use ProTools Free in 9.2 at present, using an iMic to get sound in and out. Are there latency issues with Garageband?
