Ok, I know nothing about nothing when it comes to Macs and music software/equipment. We have a Mac G4, not sure what the current OS is, but I am going to get it upgraded. For my boyfriend's birthday, I am looking to find a music software production program. He had been using Cakewalk Metro up until our computer crashed a couple years ago. He really wants to get back into it, but when I looked up Cakewalk, I saw that Metro is quite outdated and most current cakewalk products are for windows. So can anyone please, please, please tell me what an equally good music software is (by the way, he makes mostly drum type electronic music via keyboards and drum machines). I would be eternally grateful. Thanks!
