>>Hey, does anyone know what Kind of signal comes out of Yamaha's breath 
controllers?  Possible 850 compatiblity?<<

>>Something weird about these controllers is that they take power between gnd 
and -15v .<<

If you search through the past few months of posts in the archives I posted 
what I measured the voltages to be.  Negative voltages are there, and none of 
the tip/ring/sleeve had ground on it.  It isn't what it seems like it should 
be.  Nobody else seems to be able to confirm or deny what I measured so 
apparently nobody has ever built anything for it.
