Wel for the moment I don’t see any other solution, than to initiate 16 (A1-A16) program slots with the same program. This will work. It should be great to have the ‘All Cannels’ midi input option, as that would be problem solved I guess.
I hope there may be a solution in the form of a Lua script, so I can make an Multidimensional polyphonic expression (MPE)instrument library 
I’ll dive into that soon!
