The tap tempo appears when you have a delay set up as FX 1 or 2.you need to set it on the desk and then it will be on Qupad.
The soft keys are mute groups on the app.Both of these features work really well and have just about made going back to the desk not necessary at all-so now I just sit at the bar!
Oh and having the battery % and clock visible is brilliant!
