Pretty sure its the latest version of EOF. When you input a tempo change it changes it for every bar until you input the next tempo change, for instance if your tempo on the first bar was 135bpm and your tempo shifted to 200bpm at bar 24 for the chorus then shifted back to 135bpm at the end of the chorus, (let's say bar 32) then everything between bar 24 and bar 32 would be 200bpm without you having to specify it more than once. I think the problem lies in RS Toolkit where it only allows you to specify one tempo for the song.
