Diki I'm a qualified music teacher/sound engineer and semi pro musician so I know what it means.
Each registration could have a different tempo set to it so by pressing each of the 8 buttons at a certain time it would appear that the tempo is altering. It was only a quick idea anyway as I was at work when replying to it.
Also pressing the ending button twice (very quickly) does give a slower ending on 5 styles I've just tried
