Hey Steve,
Use the latest host, and go to the host window and click on the HA control. On the first row, select "Yamaha RIO/TIO". The next drop-down, it should detect the mac address, so choose the (only) one. Now set the starting channel # (1?), and 16 channels.
Now use the WDL I posted in the other section for your channel strip, and you should have head amp and gain control right within AMP!
