Hi U.D.
-Your correct-on my SD1, The Mic 1/Mic 2 Aux outputs are not controlled by the master slider. The only 'extra' you can get is internal Vocalizer can be sent with Mic l to the Aux Mic 1 output. I'm using a digitech Vocalist VR-so this arrangement is of no help.It would have been great if Ketron could have supplied one separate Aux Mic output - to include internal effects.The SD1 can be set up so the mic has no effects included when the arranger is off. Of course this feature is only available when Mic info is mixed in the main output controlled by the Master Slider. Had Ketron supplied a separate aux mic output with effects, it would have been great-cause I would have used it & then I would not have to use a separate effects on/off footswitch.
