First tried Roon complete on my mac map, then i tried roon core on my mbp and my iPhone to remote. It seems i don’t have all the same setting on the iOS. Example, i can’t choose the dsd upsampling, my dac (questyle) now con only play dsd convert to ppm because when i tried to choose dop i can’t validate this choice…
You need to use your mac to adjust Roon’s DSP settings. The iPhone doesn’t have enough screen size to show the DSP window in it’s current incarnation and thus is unavailable as you’ve found.
You can have core and remote both on your mbp. Just install regular roon as well now that you have core installed. You only use it as a remote when you need it.
You are still doing that in a sense. You leave the light core running 24/7 on your mbp and only open the full GUI Roon on your mbp when you want to do a config change, browse or control the core. When away from your mbp you control the core from your iPhone.
