I don't know the details of BC3 but only BC2. The BC2 already outputs a
control voltage that can be used in the A-100. Maybe some amplification and
offset correction is necessary to obtain the full range of some modules as
it outputs only about 3V difference (~ +1...4 V as far as I remember). E.g.
a slightly modified A-138 could do this job (increased amplification by
changing one resistor of the module).
