Hi,
Yes, plays perfect in Garage band. I just tried, it's playing the original midi file I downloaded from Musicscore - without touching the channels. I just went back to the manual and hooked up the cable following the steps exactly. But I am totally lost now. It says to configure music software settings in your music software program. So, I googled how to do this in Garage band (I'm totally unfamiliar with this program). But there's no indication that it's recognizing the keyboard. Even after I plugged in the cables, I thought something would pop up on my Mac showing that I had connected to an external device. Just for the heck of it, I tried following the instructions to set up the MIDI settings on the keyboard, but they are totally confusing. I guess and put in the navigation channel to 4. I tried playing the song but it plays through my computer. I'll have to contact Casio tomorrow and see if they can help. I feel like I've already imposed upon you - this is way over my head. I appreciate all your help! :))
