How can I change the key of my Custom Backing Track?

In order to change the key of your Custom Backing Track, you just need to click on the arrows next to the "Add to cart" button.

When you have selected your key, click on "Reload" and your new Custom Backing Track will be generated accordingly.

What happens if I've already purchased the tracks?

From your account, under "My Files", you just need to click "Change". The "classic" interface will show up and from there, the instructions are the same.
