I wanted to use the Aux Sends but they don't appear - there are no little Aux tabs on the bottom of the STM1632 graphic in the routing window (as they are in the manual). How do I switch these on ?
Click the AUX tab to go to the Aux page. In the bottom you'll se the 4 ret. faders. Above them there are "Int" tabs, selected by default, in wich case you can directly "insert" your aux fx. If you click and deselect the Int. tabs, I/O's will appear externally in the Routing window mixer panel.
