HOW DOES THIS WORK
Before I pull out my hair, I am going to try to seek some help from my fellow Mac lovers. I am trying to figure out this GarageBand application. I don't have any instruments (other than my trusty trombone), so other than a microphone for the vocals and live instruments, is there away to put music into the system without the use of a keyboard or MIDI devices?
