Anyone have any thoughts about the benefit of using the iPad app iRFR? It seems it hasn't been updated since Oct. 2107 or so. Do they still support it? Other thoughts?
Yes, they do. Version 3.0.1 is currently in beta.
oscRFR by Alien Stagecraft is an alternative.
Or just get TouchOSC and create your own layouts (or use the one from the ETClabs Github), which is the cheapest option of the three.I use TouchOSC with selfmade layouts and as of yet, I am completely saftisfied.
