For those who also use their ipads as work devices, the email administrator can disable the auto-lock "never" option. My work does, and that means my Studio One app annoyingly goes to sleep after 5 mins max and I have to "wake-up" the device and punch in my passcode to get it back up.
Specific apps can be programmed to disable auto-lock (like Google Maps and YouTube does), which is particularly important for an app like Studio One. It is very annoying to be listening to a mix or recording a long take and have the screen go to sleep. I am sure very few users would ever want this to happen - especially those like me that can't do anything about it without quitting my job. It would help to have the app provide that it never auto-locks.
