The old QU series supports shutdown via MIDI, perfect for installations with a control system (Crestron, Extron, Companion or others) where power control is already integrated.
This is something I’m missing from the new QU series - that way it could be a true replacement for an analog console. No need to think about it, perfect especially for operators which just push faders.
The old command fits in the new MIDI command spec, I would love to see it implemented
