Hi, you may also simply click on tempo (Bpm up center) while Song states are shown in the left column.
On the bottom left, State Behavior will now let you check:
Time signature
Tempo
Master Transport
Once checked, those will be memorized with song states.
Save state 1 with 80 bmp
Save States 2-5 with 160 and you’re good to go.
To set up what Igbro described you need to have the tempo state behavior checked for the metronome in the song. To see it click on the metronome strip tempo button. For each state set the tempo, cycle through the states to check it’s right and save the song. No bindings required.
