Hello all
Is there a way to 'tie' multiple tracks to one pro channel?
My instance:
I have several backup harmony vocals that could benefit the same eq/etc.
If not, then is there a way to copy pro channel settings from one pro channel to the other...or possibly, while I'm dialing in a setting on one, it will duplicate those settings to other pro channels?

Thank you for any input

Just use an aux track or bus

Hi - You can do both! 
  1) Create an Aux Track and set each tracks OUT to the Aux Track's IN. Use Pro channel in Aux Track.
  2) You can set up a Pro Ch in one track, and then save the whole Pro Ch as a Pro Channel Preset. (to do that move your cursor to the top of the Pro Ch & you will see the Save & Load folder icons).
Cheers 

But wait! There's more!! (inside joke for "Friday's Tip of the Week" followers...after all, it is Friday). 
 
I often use Takes Lanes to do "massed" vocals, like 10 or 12 voices for a chorus. Then the ProChannel for the Parent Track (not to be confused with the ancient Disney movie, "The Parent Trap") takes care of the processing.

You make it sound so easy...
Your answer only revealed more questions.
I'll look to the manual/youtube for this. I know I need to do much of the footwork myself. I'm new to platinum...any daw for that matter.

Oh! Do I need to watch the movie first?

You can save the pro channel settings as a preset. Then add it to everything.
