Roland Music Player MT-90U Remote control only. Since I was operating the MT-90U only with the main unit, the remote control is new and unused. (The MT-90U supports USB memory and can play not only music data but also WAV and MP3 files. It comes with a dedicated remote control, allowing you to play and stop, as well as control the volume, from a distance.)
