I'm having a strange thing happening maybe you guys (and girls if 
there are any out there) can help me...

Here's the patch... a-111 -> vca -> vc mixer -> out.

when I send a cv signal to my a-110 cv1 input via the a-180 multiple 
the a-111 tracks! The a-111 does not track when the cv signal is sent 
directly to the a-110 cv1 input.

In a similar phenomenon the a-111 tracks when I input an lfo to the 
cv1 input on the a-110 directly.

why does it not track when I input control voltage directly to the a-
110 cv1 input?

To troubleshoot I changed out all of the cables (no change) and 
removed the a-180 mult from the chasis (no change). I even tried 
using different cables and connectors from my mcv4! I really want to 
know how signal is getting to the system buss in some configurations 
but not in others!
Help please!
