This is great news and will give me the opportunity to get rid of my shitty self built audio mixers that I made for this purpose
What does auxilliary bypass mean? That the aux in is send striaght to the ouptut, bypassind ADC/DAC?
I'd still like to add that a audio mixer shield might still be a cool thing though. Maybe in combination with preamp shields for all us instrumental freaks that wanna hook like a mic, piezo, and say a synth all to the same input.
EDIT: One more question it seems you could have balanced in and the aux in at the same time. if thats the case could I have the onboard jacks for balanced I O and add the aux in via pins?
