The simplest you can do is just press "Lock" button in the Main section, to lock left and right channel of E-MU output. Fader 9 continue control just left one, but since they are locked it will work as expected.
If you go "Master" bus approach, the preset has to be modified. You don't need any new strips, just create a new bus "Master", move it to the first position (in the Track view) and assign its output to your usual hardware output. Everything else should be routed to that bus.
Open AZ Controller GUI, click on "Logic" tab, select "_fFaderPar(_Ch)" in the Logic Control section, click on "_Ch:9 - WAI Master Volume" action in the list, in the Action configuration section change "Master" to "Bus" and "<First in WAI>" to "<First>".
If you don't want "Master" bus always in the first position... Click on "Options" Tab, in "Software States" section select "<New set>" (in the first drop box), type "_BusName" in the input bos right of it, press "Save". Modify "Default" in the input box to "Master" and press "Save" again. Return to the "Logic" tab and change "<First>" to "_BusName". "Master" will appear on the right (since that is the only choice).
