I have these loops that were in .wav format. I put them in the Apple loops folder with all the other loops that GarageBand has. They didn't show up in GarageBand...so i converted them to aiff with iTunes....still didn't work. So I converted them to MP3....still didn't work. all the real loops in the folder are in .aif format, but the pic shows a quicktime image and says "aifc". So how to I get all my loops to this right format. Or am i just doing something wrong with the other formats?
