Thank you so much ekohn00. Thats exactly what I want!
My server is a Roon Nucleus, my endpoint is the node. I want the Control 4 remote to control volume on my processor and transport controls (pause, skip track, etc...) for Roon. I browse and select my music using the Roon app on my ipad. The bluesound node is "just there" so to speak as an endpoint. As for making sure the bluesound node is set up correctly, Roon works perfectly fine on it now so no issues there, has worked perfect for over a year. Sows up as an endpoint. Unless I am missing something I believe I am all good there. Node and Roon was very easy to set up. Its just moving from the Harmony setup to Control 4 is the challenge. As mentioned the installer surprisingly did not know what roon was and looks like he just set it up for the bluesound node instead of Roon.
Thank you again, I will search for your post. I did a search before posting this and could not find anything. I will look again. I am new to the forum (first post) so if your feeling really kind and have time shoot me a link to the post you referenced. Dont want to seem greedy with your helpfulness though. Your post got me heading in the right direction and is much appreciated. My heart kind of sunk after spending a bunch of cash on a C4 setup and installation to have this function not work they way I thought it could. Now I know it can.
