I have just finished a project and rendered the final result but I have noticed an audible 'click' at a tempo change point from 150 bpm to 90 bpm. I have not found a way of removing this so wanted to try separating the slower sections I had inserted in order to render both parts of the song separately and then try joining them up afterwards. (I have previously used Audacity to do this. However, I found that the sections are now ghosted and cannot be moved, resized or anything. I am running Acid Pro 8 on Windows 10 64-bit
