With the Pioneer RB-VS1-K Control Vinyl Timecode Black your Rekordbox DVS system is complete. You use a DVS system to control your digital record collection with a physical vinyl record. This means that you do not need to have an extensive record collection to learn how to spin with vinyl. You select on your laptop the mp3 or wav file of the song you want to play. Then you beat the music on your turntable with the control vinyl. This makes your turntable work like a DJ controller. To get the system working, you need the DVS license from Rekordbox and an audio interface. The timecode plate is suitable for the Pioneer PLX-1000 and the PLX-500.
