[sdiy] MIDI control syntax to debug 16 bits values on the MIDI steam using MIDI-OX MIDI monitor ?

None in 2 bytes. Read the MIDI spec.

You're going to have to make your own. Either send 3 CC 7 bit values and 
make 16 bits out of that or make a SYSEX message that takes 3, 7 bit 
data bytes and put that into 16 bits.

Good luck.
