Hey thanks so much for your patience, I think i’ve got. I’ve successfully mapped different values of the same parameter to three different hot switches. However I’m now confused by the display of what I’m presuming is the Overlay.  Each of the switches are mapped to Hotswitch 1,2 and 3 but regardless of which one I press I get the same momentary message at the bottom of the screen: P/programme name/hotswtich on or off.  I was expecting the algorithm name with the parameter value or something similar.
