I see, apparently I misunderstood the scope the of global sensitivity. I thought it was, well, global, not per preset.
As for the playing, yes, I'm trying to play with just my fingers and relatively light touches. This might not work so well, I need to try some more, but it wasn't the principal reason I got a BopPad in the first place.
To provide a bit of context, I'm using the Earmaster app on an iPad for finger exercises. Tapping regular rhythms with alternating fingers and things like that. Previously, I've been tapping on the iPad's screen. Now that I have a BopPad, I was trying to tap on that instead. In my attempts so far this didn't work very well, but I'll experiment more with various settings. Beside that, the BopPad works fine when connected to the iPad.
