Cubasis keeps running after closing app

When I exit Cubasis app on ipad it shows that cubasis is still recording. I read the manual which said to double tap home, then hold app to close. When I hold down the app it only opens the program again. Any suggestions?

After double tapping the home key
iOS 7 slide the app up to close
iOS earlier hold the app until the x appears then tap the x

It worked. Thanks
