Since this is a rehearsal for a sub gig, not possible. I offered my deck for this rehearsal and the leader passed. Too bad. Not looking forward to this from all that I’ve heard about how it doesn’t work well.You can NEVER be tight live over distance. It is simply impossible to surmount physics. It is not (yet?, or ever?) possible to convey anything over distance without the corresponding time it takes to do so.
The only option is to swap tracks and add parts to be mixed later.
