It seems that this interface still has the old OSC addresses that were used in previous versions. If you click the setting you want to change; after selecting the edit OSC tab, (similar to the midi mapping technique) then you can see the new address in the window on the right. You can then copy the text of the new address into the lemur editor for each one. Be sure to re-save the template after the changes and re-transfer to your iPad. Unfortunately it's pretty time consuming to do one by one.
