OK. I am the newbie of newbies. I currently have an HP with cakewalk that I use to record keyboard and guitar with. It stopped working. My daughter mentioned that she has an IMac 24 inch that I can have. I know nothing about the IMac and am confused what I will need to record, My old system has an EMU card in it which I plug my mixer cables into. Do I need that kind of card with the Imac? Is there recording software already installed? I just do simple recordings layering tracks. I am truly computer challenged and still lost by the "midi" term. I have heard Mac is the way to go, so I dont want to miss this opportunity. Thanks in advance for any help!
