Hello,

One fun thing can be done in order to get 4 insert effects for one part, instead of 2 max.

1) In Part Common Routing Output Select, select Assign (L or R or L&R)
2) Plug a short jack wire between Assign and Audio In.
3) In Audio In Routing, select InsA and InsB effects : so, all in all 4 Insert Effects.

That's it !
