PBJ-From my somewhat limited research, there is/should be a way to use the ipad/phone/tablet to control a pc or laptop. My PC is across the house and running on a system in that room. I am using an ipad to run TIDAL HiFi on my main rig, with the ipad sending a digital signal to the DAC. I hope to find a way to use the iphone (or something) to remotely operate the ipad. Otherwise I need to find a 20' lighting cable (not likely to be cheap, if available), or get off my butt to make changes in programming (just like vinyl, but why run digital if its manually operated?).
With Spotify, I have the app on both the iphone and ipad and with both running, the phone syncs and operates as a remote for the ipad (slick trick-I didn't do anything to make that happen).
Trying to get the same operation with TIDAL-no luck so far. In fact each device will operate independently
