As a professional composer I tend to like to leave my studio "on" much of the time, and I'm surprised to see there's no kind of time out or sleep mode for the MK3 keyboards.
Perhaps the LEDs / Display are robust enough that they can be left on indefinitely - I genuinely don't know - but it seems intuitive that a "time out" should nevertheless kick in to turn these elements off, if only to save power, after some period of non-interaction with the device. Thoughts?
