Hi!    I just got a wk 7600 and I am in love! This is the first midi/workstation I've ever used so it's been a lot of learning! I have connected my usb to my PC and downloaded the data manager and was able to transfer my song sequencer files to my computer however, they transferred as CMS files. I am not able to open or access them. How do I transfer files that I can open and listen to and then upload into garage band?   Thank you for your help! FJ
