I would like to connect a breath controller to my soon arriving
system. Currently I have Yamaha BC3, which is a passive capacitor
based device. I already have a MIDI solution (Yamaha SY99 + A-190).
However, in my experience, MIDI isn't fast or accurate enough
with breath controllers. How could I a make direct analog connection

Some technical info about breath controllers is found here:

ransducers.pdf
No specs though.
