Yea the only thing that comes across the RSD into Simpl are the virtual keypoad button presses. I've never seen any of the other button states come across (P+H, multi tap, etc). it doesnt send over the Held condition. You should do the opposite way as Eric says- import a RSD into D3 and then you can tie whatever Simpl signal you have to the Held case of the D3 button you need.??
