Hi! Music is a serious hobby for me, but a hobby still... Recording is part of it. I record small personal projects for myself and I record my band (in our rehearsal space, which is the drummer's basement). Plugged into my computer is a Tascam US-1800, which allows me to record the whole band live, with different trances for each instruments (multiple tracks for drums). Bass is usually recorded with a SansAmp RBI, I have an extra preamp for vocals (plus bandmates have extra gear. I'm currently using an 8 year old basic (read "entry level") MacBook and GarageBand. I've never needed more then GarageBand for the type of projects I'm doing and it never failed, really (some "disk too slow" situations in the past and more recently, GarageBand froze in a recording session, but nothing too serious and no regular problems). But, well, the computer is getting old so I'm thinking of getting a new one. I can't update softwares anymore with mine, I don't have the minimum requirements anymore! I like Macs, and I plan on using GarageBand, and on moving around. My question, considering everything works well (except for small issues, which I suspect will not get better with time) , would a basic MacBook Air do the trick? Also, are my old GarageBand projects work with the new version?
