Export/Import Tempo track isn't giving same tempi

Exporting the tempo track from a full score into an empty template changes the tempi. Any way to avoid this from happening?

MIDI doesn’t provide a way of specifying that the metronome mark should use any unit other than a quarter (crotchet), so unfortunately that’s what you get.

OK, thanks for clarifying. I didn’t realise that a tempo track was actually a midi file. I haven’t used this feature so often yet.
