on djay: how to start both turntable at the same time?

The band (die tödliche doris) had this great idea to record 2 different vinyls. If you listen to each album indepedently, it doesn’t make any sense. You have to listen to both vinyls at the same time in order to listen the whole ALBUM.
I have both albums in mp3. Now, I can finally listen to the whole ALBUM. But how can I start both turntables at the same time on DJAY?

Hi Céline,

Make sure the crossfader is in the middle and then press the SPACE BAR on your keyboard.
