I need to set up a song format so that the timebase is in seconds at the start and then switches to bars part way through. Is that possible? If not, can I merge the two pieces in the project environment, one having a timebase in seconds and the other set to bars? In case you're wondering why, I have some narration at the start which must be set to seconds and then, when the music portion begins I want to switch to bars. Thanks in advance for whatever advice you can offer.
