Use this tool to sharpen your beat-matching skills!
You will hear 2 drum loops playing out of sync, try to match them up so they sound good.
This will be easier with headphones, one loop will play in each ear.
In Freestyle mode you can just play around, using the Auto-Match and BPM Display tools to help you.
In Training mode these tools are hidden, you are on your own! When you are happy with your mix click the 'Analyse' button to see how you did.
