It won’t allow me to do this. 
Here is step by step what I’ve done → new project file, blank slate (1 stereo in, 2 mono ins)
1)Created Instrument track with Loopmash
2)Created Group track
3)Created Audio (stereo) track
4)Went to mixconsole and set both routing ‘in’ and ‘out’ options to “no bus” for the Group and Audio tracks to start fresh w/ no feedback loop.
Now…
It will allow me to route the Loopmash instrument to the Group, but I cannot route Group as the ‘in’ to the Audio track.
The only options it gives me, is to route the Audio track ‘out’ to the Group track. (among the other obvious options “no bus” and “stereo out”)
Very confused !
