hello,

i agree that osc is better than midi for lot's of aplications, but this matrix is bias.

-a typical exemple in osc is more like this : 

/wii/ir/x....,f......
where . is not a letter/number
so i don't think it's "human readable"

-The "Hardware Transport Independent" is in direct conflict with "Data rate":
osc is hardware transport independant, so we can use osc with a 9,6Kb/s serial line.
                           
-Curent OSC transport layer is not really microcontroller friendly. 
few dollars microcontroller can easilly deal with midi, but not with curent osc implementation.
a osc implementation on a microcontroler is lots more difficul than midi.

-according to this matrix, OSC is for "music, video, robotic and more", midi is limited to music.
but personally, i saw more "video,robotics and more" aplication using midi than osc.

-where does the 20ms midi clock-sync accuracy theorical limit?

-this chart does not speak about the osc typetag : when implementing a osc recever, why you have to test for float or int if you wish to receive 0?

- i would have prefer to see a typical data rate better than the theorical one.

- i would also loved to see in this matrix a typical loopback latency on curent hardware and software of OSC vs MIDI

best
