Before Roon I only had my main speakers in the living room. Now I also have a kitchen zone, a bathroom zone, and a study zone. I use zones to play the same music in two or more zones at the same time and I use “transfer zone” when I want to take the music with me to another room. I have never had the use for playing two different pieces of music at the same time.
It seems to me that the user interface for zones favors playing different music in different zones at the same time, whereas grouping zones requires going one menu deeper and clicking save after ticking off boxes.
My request for the zone UI would be to move the grouping feature out to the zone selection UI and make it something like the layer interface in Photoshop where you can click layers on and off from visibility. I realize the analogy is not precise. In the case of Roon all “layers” or zones would be playing the same music. But the feeling of clicking zones on and off seems like the most simple way to do zones. The one music number playing in the entire system would be jumping or grouping seamlessly between zones.
It could also be a way to transfer zones as you would just click the zone you want to transfer to and then click the original zone off (or mayby even drag and drop).
In my smallish setup in my smallish apartment 9 times out of 10 it is the same two zones I switch between or group together so a way to define a “next most used zone” setting would be helpful. The logic would be: If I play in one zone (eg. living room zone) there can be a user defined next zone to that (in my case the kitchen zone). And reverse my kitchen zones “next zone” would be the living room. In that way I could transfer or group to the “next zone” with one button. That would take care of most of my zone grouping or switching with just one button.
Another nice touch would be keyboard shortcuts for zones. That would your Harmony remote number buttons could be used to switch zones on and off.
There is probably a technical developer nightmare underneath this idea that I don’t know anything about. The idea also favors those only playing one track at a time. And there are probably other network aspects that I haven’t thought through. Just my thoughts on simplifying zones. Feedback is most welcome.
