Yes.
Still, is the tempo 0, or whatever it is supposed to be at the point
where the transport is holding?
I find it rather useful when the latter is assumed, since it makes
the fact that audio processing continues a lot more useful. You can
still jam on and have tempo and beat sync effects roll, as if you
were looping an empty section in the song. As soon as you start the
sequencer again, though, beat sync effects will instantly lock to the
timeline.
