Yes, well know but when wrote "output from a buss" is it the bus itself (before master module output) or the output of master module of the buss?
The documentation is not clear on this point.
The busses are adding points for the channels assigned to them. The signal on the buss has to pass through a master module to the output. There is no output directly from the buss.
OK you confirm what I suspect to be. Loopback provide MAster bus output as input source.
There is one case output is directly comming from the buss, it is the cascading but this is another story completely managed by Cascade fonction.
I have the opportunity to buy a DM-3200 at a good price and it is the reason I look deeply at the routing to check if it will be convenient for me. At this moment Yes.
Many thank's.
