Question

How do I route the Main Out in Studio One to more than one output at the same time on the Quantum (or other interface).  I need to send to a sub, the sub does not have stereo outs, and monitors do not have pass troughs.  Need to send the same signal to both outs controlled by one fader.

Answer 1

You may be able to achieve what you want by using a Pipeline plugin post fader, sending a mult to another output.

Another way would be to use a pre-Master group bus, staged before the master, to use ordinary aux sends to multiple outputs.
