peter Can you attach a screenshot? I think the upper position could be correct because the play buttons needs to be placed above the iOS handle.
You have fixed the jumping, but now the issue is whenever you change orientation the button sections goes to the upper section of the jump and remains there , so the jumping has stopped but the problem is still there in a different form .
As you open the software at first, the buttons are as they should in the lower position , as you change orientation the buttons get raised and stay there untill you exit the program again.


Another thing, as you can see my loops are small and hard to choose, I think the permanent loop selection button would be a lot more useful being a select button as you always need a selection of loops but you hardly ever need a permanent loop, you can always tap once on select button to get one loop and keep doing this till you want to loop no more, but you can’t select different loops at all which is more important when using loops.It makes more sense.
