Not at all, and I tried it with the Aux/Eff|L/R monitor switch in both positions in case it had been mislabelled. Neither the Effect nor the Aux Out jacks produced any sound or meter response when I ran my drum machine through them. Which is odd, because I know the effect send works.
For the record.
I plugged the mono output of the drum machine straight in to the Effect Out Jack
I set the Aux/Eff|L/R switch in the monitor section to Aux/Eff
I switched the monitor source in the tape section to Effect
Nothing (and yes, the drum machine was playing and, no it wasn't an empty pattern)
Then I did the same but with the drum machine plugged into the Aux Out jack and Aux selected as the monitor source. Again... Nothing.
I wonder if that might be because, as outputs, they're expecting an internal source?
