Hmmm.... strange.

You might have a problem. Since your sysex spec uses C4 (-60) through 0C 
(12), the numbers match up (as opposed to, say, 0x00 to represent -60 
and 0x49 to represent 12) so that the widget/param-model doesn't have to 
add/subtract anything to the number before it stores it. The only tricky 
part is if the widgets will try to store negative values... and if the 
param-models handle it correctly.

I might take a look later.
