The metronome audio is routed before the effects on Out 1/2 in Superior Drummer 3.0.1. This makes the metronome unusable with some effects on Out 1/2. A workaround is to map the buses to higher output channels such as 3/4 and higher, but that’s not a long-term solution.
I suggest to mix the metronome after the effects on Out 1/2.
Thanks,
