Hey, I used to use Ableton Live to do all of my recording (I got it free with a line6 usb interface I bought). In that program, I was able to drag and drop midi files and attach instruments to them. After attaching the instrument, I was then able to switch out the basic drum samples for my own recorded samples. I've figured out how to attach some of Logic's drum sets to my midi files, but I cannot figure out how to switch the samples out for my own, if it's even possible. Can anybody help me out?
