It says styles are enabled. I go to create styles and it is only for a midi file. This is an mp3 recording of someone playing guitar and singing and I just want to add like drums and other instruments to it. I was going to try and go to the top where it says bass, piano, drums, etc and choose drums, then add real drums and choose one from the list. When I click on one and click ok it does not play with the song when I click play. It says NA beside every one of the realtrack options. How do I add one to a song that I opened which was pre-recorded and not a sample track from the biab?
