A couple of possiblities: what are you using to place the CV/Gate
onto the bus in the first place These bus lines are to allow, say,
an A-190 to supply its CV to A-110s, and its gate to A-140s without
the need for external patch cords (also you can feed signals onto the
bus using an A-185 bus access module). If you have either of these
set-ups and still no joy AND your kit is second-hand, then its
possible the previous owner may have removed a wire link on the A-
110s which is needed (if this is the case, get back to me).

All the jumpers do is split the bus board in half when they are
removed, so that for example you can have *2* A-190s controlling
separate VCOs attached to the (separate) sides of the bus.

Nothing on the bus board is

Sorry, don't know much about other synths, but if you are attempting
to send CVs to the A-110s and gate to the A-140 from the Prosolo,
then maybe you do need the A-185!
