There really is no MIDI standard as to the placement of middle C, John.

Some designate C4 (note number 60), yet others can be C5 and on some controllers as well as softwares, it may also be assignable, though most users likely never realize that.

I just figure out which is what and, for lighting purposes, "transpose" the octave accordingly.

Playing music on the darn things is a different story, for that I have to delve inside controller or software menus because I like my middle C to be, well, in the middle unless I've programmed some sort of dual voice split.
