Beds on voicetrack
When creating a voicetrack you can set a bed, which would be a pre-faded song (faded by 8dB for example). This will play a background bed jingle during a voicetrack.
We can do this live by using a "bed" group, which we put in the play log instead of a break note, then we speak over it. However we can't do it easily on voicetracks.
