[sdiy] breath controller input

[Theo]

Hi Ruud
I sent you the DX7 schemas as a seperate mail off list.
You can see there that the BC input is a kind of CV input, but wants a
NEGATIVE going CV.

Besides BC there may also be a volume pedal input you may want to promote to
CV in.
Like wise for the MOD and Pitch bent wheels.
Note the CV inputs don't have to replace the wheels but may be added to
them.

HTH
