I'm trying to script Logic Pro X only using keyboard commands. So far I can do everything I need to do except change the tempo. Is there anyway to change the tempo only using the keyboard?
The only way it seems to be possible is by using 'Tempo Operations', which you can assign a keyboard shortcut to. Although it's possible, it's certainly not ideal. You would have to hit your chosen command to bring up 'Tempo Operations', then alter the start and end values for 'Position' and the start and end values for 'Tempo' by tabbing through the value boxes (For position, you could enter say '1000', which would apply the tempo to the end of your project unless it exceeded 1000 bars. Also, make sure the start and end tempos are the same).
Like I said, it's not just a simple tap of a command, but it looks like the only way to do it using only your keyboard.
