I've playing around with my cousin on Apple's Garage Band, and I was pretty impressed with it. Unfortunately, I have a pc, not a mac. Is there any way I can get Garage Band for my computer?
There is not. It does now come on iPad though.
Mixcraft is similar, though the full version isn't free.
If you need a DAW on PC you're not really gonna get much for free. StudioOne has a free version but it's pretty handicapped. You're best of with REAPER for about $50.
Mixcraft is pretty close and is on PC. If you're on a budget Cakewalk Music Creator 6 is on sale for $25 on Steam.
