Here's what's going on.
The only way to make the variations go up or down when you hit fill is by turning on the "jump" feature. You will find a button with this name. If off, the variations just stay right where they are and when on, if you push the fill 1 the variation goes up, fill 2 variation goes down and fill 3 the variation stays right where it's at. Be carfull though that when in the "jump" light "on" possition, you will not get an intro but rather an ending at the beginning and you will get a intro instead of an ending when you have already started the style playing.
the second issue is because of the sample loops. If the style does not contain a sample loop, your tempo control in fully functional from the slowest to the fastest values, but if there was a loop, you may only change the tempo within the range ketron allows because anything slower would cause the style to sound bad. This is also the same situation with the X1. Many customers have asked why the bossanova only goes down to a certain speed and no slower and this is the reason.
