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

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.
