Screen gets dimmer and dimmer

I’m trying to use Cubasis on my iPad 4 in the front seat of my Jeep (not even in direct sunlight) and the screen is so dim that it is impossible to use Cubasis. The screen doesn’t go dim slowly, it is always dim even when indoors.
Steinberg must realize that the reason people are using the app on a mobile platform is so that they can go out of the house and make music.
I’ll have to go back to GarageBand until this issue is fixed.
