If you could send an html addition to the appropriate manufacturer that 
would be helpful. Otherwise just these:

manufacturer, card name, chip, module name, needs midi firmware

Probably best to start with that and ask some questions as you go.

yes.

There are times when people need testing done. Just monitor this list.

  Apparently upon the beginning of the barrage, the donkey broke 
discipline and panicked, toppling the cart. At that point, the rockets 
disconnected from the timer, leaving them strewn around the street. 
Tethered to the now toppled cart, the donkey was unable to escape before 
the arrival of U.S. troops.
