Is it possible to switch between external input and feedback from the menu - instead of relying on manually pluging in / out the external input cable? if not is it possible to integrate to future OS.
find myself switching between the 2 quite a lot, starting to worry about damage to the jack.
+1 that would be a nice feature
I find most menu operations extremely fiddly. I think that adding a physical switch though would be a very easy hack.
What would be nice is a function like tap tempo: hold for instance the mixer ext in button for 2 seconds and it would switch te external in, and holding again for 2 seconds back to feedback.
Just my 2cts
