I wish you could COMMAND+DRAG the already created output of a track to the input of another for quick routing. You could do this for busses too.
If the Low Latency selected path is at the top of the the bus I/O Tab, when LLM is engaged all the send busses on tracks show to be bypassed, these still pass audio although look to be bypassed.
This is the case when one of the buses is mapped to an output (chan 7&8 on the HD I/O) at the top of the bus tabs list.
We have a work around for it by leaving this bus at the top of the bus tab list.
Studio One has pipe line
Reaper has REAINSERT
And they both ping for latency. Unfortunately PROTOOLS does inserts by correspondending / matching channels and it's not good for Universal Audio users.
