All, Probably very stupid question, but I don't speak English natively, and am quite new to Logic Pro X... So, I am a solo bass player. I have an audio interface, with only one input/output, for now. I have this great loop that I recorded through a loop pedal. Now I would like to record a melody over that. I already recorded the loop, and repeated it. But now, when I want to record the melody, I would like it in a separate track, so I can separately edit it. Any ideas how to go about this? Thanks for your help!!!!
