So I've decided to try and expand beyond rapping. I've bought a yamah ez 220 (pretty basic but that's all I need for learning). Anyone know any free software (multi track) that will be good for recording to, then chopping/moving/editing bits? Also, how do I go about recording? Am I right to assume if I use a USB it'll just think of it as a midi keyboard? DO I need an audio interface or can does a cable exist to go into the phones/output and then link to my computer (such as mic in)?
