This option has been removed from uTool2. There is only one mixer setting now. It is the one applied to the monitor. You may apply the same fader values (as the mixer) to your direct outs by changing the following option : Menu -> Playback -> Multitrack Mode Options -> Outputs to Post faders If the Outputs are chosen to be Pre faders direct outs have a gain of 0dB.
Remember that when you choose the post fader option, changing the monitor level on the fly also changes your direct out levels.
