Choice to have USB output unprocessed

AFAIK you can do that already

Please chose one of the DI settings ("DI" replaces "Git") and read the documentation before raising feature requests.

it would be nice to have a choice where the USB output could be unprocessed much like the git output setting so that you could use the USB audio to feed into an iPad with another amp simulator on it and achieve dual amps

I already tried this and it works fine. Check the treat for more information.
