Have any of you guys used this? I dont have band, but I got some songs, can I use this to record my guitar playing and then add other instruments to make music? Can I also record a guitar lick, then use it as a sample to play over like, say, a techno beat? And finally, can I take any mp3 and take an instrument or part of the song and use that as a sample? Please shed some light on this Garage Band program...or are there any other programs that will let me do this such as pro tools? I jsut want to record and be able to sample things to make my own music. and is there something i need to get to record my guitar and keyboard, like a cable?
