Hi bob, i use to have a md which was easy to use basicaly plug into the computer and download from sonicstage. im looking for something similiar

I bought a mz-r410 a while ago but then realised it did not have a usb port. so i purchased cav-u5 digital converter. the problem is i cannot seem to download to my md. do i need another software? or do i need to use something else? help needed please many thanks
