In order to keep the mixer off and on there should be option to restart device without presing botom in the back.And as far as micxng chanel are concerned it would not be a bad idea to offer users the option that they too can mix 64chanel digitaly,with next update firmware. I have a studio live serio 3 32chanel mixer and i realy be happy to have that possibility to mix 64 fat chanel in daw.
