Good morning Tod
Not a stupid question at all.
If your happy with a resolution of 1/1 (bar, whole-note),
then you can use the old way.
You will however find Breeders action "Convert project markers to tempo markers" faster and better than your macro.
The new Breeder actions would be preferred if you want:
- higher resolution on your tempo-map (like quarter-notes and 8-notes), or
- would prefer linear points, or
- would like a fast workflow of adjusting time-position for individual markers, or
- have a complex project with different time-signatures
In addition there are other tempo-tools
for selecting, converting and adjusting.
Happy tempoing!
