No, I get what you're saying so maybe I didn't myself explain clearly. You cannot expect a pre-roll to change the tempo of the part before the cursor, although there's nothing wrong with asking for such an option. Currently, you can only use a metronome count in, if you need to hear the tempo after the cursor as a lead-in to recording. So yes, for what you're doing, pre-roll doesn't make sense. Use count-in instead. Alternatively, you can make the tempo shift from measures 9 to 10 gradual if you double click the tempo marker. Then at least the change from 120bpm to 125bpm at measure 10 will not seem so sudden.
