Midi Remote API documentation

I started creating my own API Script for a M-Audio keyboard controller, but when I looked at the included JavaScript documentation it is just a really simple list of methods and properties.

Is there anywhere some really extensive documentation that has more than just defining parameters named x, y, h and so on?


I have the same problem. For example:
So what is the structure of the MidiMessage object?
Can a MidiMessage be a sysex string, for example?
… and so on.
