So, if in your system all your endpoints are Meridian/Sooloos then you're fine as Roon will allow you to link them.

I don't recall anything special across zone volume levelling in Roon, but provide you have calibrated your analogue zones to be aligned with you DSP zone you should be fine.
I wish I had known this earlier. I have an MS200 which is connected to a Marantz processor which feeds second and third zones. The zones are always set for music from the MS200. On playing with Roon settings I managed to link the "room" zones with my ID40 card and took the MS200 out of the equation. Unaware of what I had "accomplished", when I next played something thru the ID40, the AirPlay zones on the Marantz for zone2 and the Denon AV receiver (which received Zone 3 output from the Marantz) came to life with full signal from the Marantz and Denon. Blew(I think) the zone 2 amps on the Denon, as the volume level thru to the mechanical wall control, was way too high.
I assume this is related to the above quoted comment about not mixing Meridian and Apple end points. Is there a place where this is discussed in detail? The last thing I was thinking about was downstream volume levels. I think I unchecked the MS200, and then checked the Denon and Marantz on the Roon settings, linking them with the ID40, just before this occurred.
