Playbeat 3 shows up in AUMs multibus support list and one can setup up several AUM tracks reading from a single Playbeat instance on outputs 2 to 9 (8 busses) BUT i didn‘t find any settings in Playbeat 3 itself to use these outputs.
I searched in Playbeat 3s mixer page where this kind of setting would belong. I tapped/doubletapped wherever it seemed appropriate to hide such a feature. Searched in the settings, on the sample editor and in the sample overview.
The manual also doesn‘t mention on how to enable output to separate busses.
So either the addition of the multiout node is wrong (if not supported by Playbeat) or Playbeat is missing a setting to enable them.
