Record a Live Loops performance in GarageBand for iPad
You can record a Live Loops performance to Tracks view. When you start recording, any cells currently playing are recorded to the corresponding track in Tracks view, from the beginning of the current song section. If you start cells playing while recording, they are recorded from the beat (time position) when they start playing. Any changes you perform to cell settings, such as adjusting the speed, pitch or direction of cells, are also recorded.
