Thanks! I couldn't remember the proper menu. I had the wrong menu (which is why I had Process with a ? indicating I wasn't sure if I was mentioning the correct menu), but I was trying to find the documentation which you linked. IOW, I know how to get it to ritardando/accelerando, but I don't want to slow down or speed up gradually. I want to go from 115 BPM to 90 BPM in one beat. This should help.
