This could be a perfect solution for a “Silent” Melodica: the second tube could be switched between the reed chamber and the outside, while the first one would always put the pressure sensor at work. What’s the purpose of the tube going to the outside? Is it just to release air? That does sound perfect! I have assembled my own Midi Melodica Would love to see this in action. Excuse my ignorance, but is this prototype currently connected to a computer?
