I'm using a 'sub-master' track for 'master' fx so post fx can be sent separately to a second headphone fx track. Each time I add a track it is necessary to untick the default send and assign a send to the sub-master. Is it possible to define a track as the 'Default send'?

I thought track templates would help you but, on checking, track templates do NOT save any sends or receives :-( There are some SWS actions that might speed up your workflow, however. Check out: SWS/S&M: Copy selected tracks sends SWS/S&M: Save default track send preferences SWS/S&M: Recall default track send preferences Also, this forum post might help:

I think I can put a solution together with this information. Thank you.
