JunXion and multiplexing


Ive got a project that needs a series of analouge and digital inputs, greater than the number on a Uno or Nano (both of which i own) also have a MUX shield for the UNO, and am using JunXion to convert serial to midi,

is it possible to use the mux shield in conjunction with JunXion?

if so how do i go about modifying the Aruino2JunXion Sketch?

many thanks for any info!!!
