I use an external soundcard with 12 outputs. I have several tracks set to External out 1/2 and several set to 3/4, etc. How can I set the master to 1/2 so that I can export all those tracks as a stereo pair?

As it is now, I have to go to each of my external out tracks and reroute it to "master".

Create a new Return channel for those channels.

Highlight the title bar of all the channels at once and crank up the send amount. It should raise them all at once.
