The implementation of the Metronome has hidden the ability to assign Tempos to Scenes. It can still be done, but it’s not as obvious as it used to be (it used to have a ‘Scene’ Mode, now it doesn’t) and the manuals don’t describe how to do it.
If you want different Tempos across Scenes, go to the Tempo/Metronome page and set the Tempo Mode to ‘Preset.’
Now long-press the Tempo parameter control till the ABCD icon shows. Then set the tempo for each scene by using the arrow box w/ Scene Letters in the upper right corner next to the ‘check mark’ icon.
Similar process thru Cortex Control (also not describe in its manual)
