Very disappointed. Wish I could get my money back. Hard to figure out. Clumsy to use. Can’t just add songs via Dropbox. Must use clumsy FTP from computer which means typing in Http address into computer and uploading file (poorly explained process) But they let you upload from iPod (if anyone’s still got one of those). Outdated and difficult to use. Not intuitive. Try Backpack. Muck simpler and better... ## Frequently asked questions about Instant Audio Studio Cartwall ### What is Instant Audio Studio Cartwall used for?
