Siemens A65 data usb cable n ringtones

Hi there I was hoping if anyone can tell me if you can transfer .wavs and .mid / midi files and any more audio files possibly - via a usb dca-510 and the siemens firmware (between the phone and a PC of course). Then use them as ringtones? I saw the wavs on the phone and mids but that was all. I havent bought a data cable yet. Thanks in advance
