This tutorial is very helpful for those looking to remix music in garageband! Personally, even I have had to look this up in the past and it is much simpler than you would think! This tutorial is also very quick- so if you only have a few minutes to learn a new skill and are interested in learning a helpful feature of garageband- this is the one for you! Personally I’m really happy that I watched this a while ago and taught myself this skill which is super helpful for making music since you can record something slowly and speed it up to fit your desired tempo!
