Using knobs on streamdeck+ to control Yamaha's R Remote

Hi friends,

I have been tasked by my boss to research the possibility of controlling Yamaha R Remote's virtual knobs (to remotely adjust head amp gain levels on Tio and Rio hardware without tying us to the need for using Yamaha boards). Before I get too deep into the weeds I'm curious if anyone has done this, and what the most reliable method would be. Upon a cursory glance it looks like there are some macros built into sound flow that might be the ticket, but I'm having a hard time wrapping my head around how to incrementally adjust the volume of the knobs, considering the macros ask for defined X and Y coordinates for start (which is easy), and end points (which would have to be variable to be able to adjust correctly, in my estimation).

Perhaps I'm having a failure of logic here; as you all might have surmised by this point I am an audio person and not in any way inclined toward programming.

The other piece of the puzzle for me is an elegant way of banking between the 16 gain knobs on R Remote that correspond to head amp gain, so that those can be mapped to knobs on SD+ for intuitive adjustment.

Your suggestions and feedback are welcome and appreciated!

Many thanks in advance,
Charlie
