same display, same graphical style, but of course all functions need to be made for specific project
which means - 4 inputs, 64 step volume, encoder on front for volume - short press for incremental input change, long press PowerOn/Power Off
power On/Off is operating small relay on board which is firing either fat main mains relay ( or SS Relay) , proper muting of FE outputs must be sequenced, etc etc
of course fancy remote covering all functions
so, in short - Display and Arduino are the same as for IPumpkin, but code and number of operated functions different enough
well, that's short explanation of all things logical
now - care to clarify your question - are you asking - is it possble for someone else to make own Logic Module ..... or you are simply expressing wish for differently looking display?
