thanks for the A/D idea.
i only need to scan 4 inputs max, so maybe i would scale an incoming
+/-5v CV to a range which would just affect the 2 lsbs of the LM3914,
then use the outputs to index a cmos 4013 analogue mux or something.
the blacet scanner has configurable overlap on the inputs, so it must
have a different approach.
