I've been scouring the latest bug fixes, and it says that tempo automation has been updated. Though it makes perfect sense, I wasn't aware you COULD automate tempo. I tried RMB'ing on the tool in the window but I can't get the parameter window to come up, like it does on a loopPlayer etc.
Can anyone point me in the right direction a.k.a. the thread that's already answered this question? Thanks, and happy mixing!
