I am a programmer and a musician. I was a guitar teacher before I became a programmer. The Job of a top quality Programmer is to make life easier for the client not harder. If they can't do this they should not be a programmer. They should not be using computer limitations to decide what middle C is. Musicians are the ones who decide this. Along the same line they should not be looking at what other programmers have done to decide. Musicians have been around a lot longer than programmers. The people who designed the midi table are clearly top level programmers who understand what I just wrote. If musicians are a bit undecided then a top level programmer needs to make Middle C an option. Based upon Google info and some comments in this thread it appears that 99% of modern musicians have decided Middle C is the C below A 440 (it appears as though 99% of musicians agree with the table).

Here are more links pointing at C4 as middle C.

History of pitch standards in Western music

Obviously what matters is the present but that info is in this wiki.
It says "The most common modern tuning standard uses 440 Hz for A above middle C as a reference note"
