The reason why this is useful for me is thus:
I use Studio1 to "take notes" as it were, of musical ideas.
And further I am primarily a guitar player, so quickly laying down some beats is a pain.
Sometimes in the jotting down process, it is useful to have metronome with the right accents and signature to help avoid "destroying the mood" and also to help keep things tight while recording.
I've gone as far as creating a home template with a drum loop, but it's too much of a straight-jacket for the benefit.
