I'm sorry for such a naive question, but I'm getting close to having
enough modules in my first ever modular to be able to make a noise &
have realised that I don't know how to control the A-100 either from
another CV/Gate synth, or from a dedicated CV/Gate keyboard - is there
a module I need? I can also see that there is a CV/Gate connection via
the Bus Boards in my G6 Suitcase and it looks like the two boards can
be jumpered - is that correct? Thanks, Matt

It depends on what your trying to achieve but if for example you want a
musical output you would patch it like so:
 
keyboard CV out - to - VCO CV1 (fixed 1/V input)
keyboard gate out - to - Envelope gate in
 
a simple patch then would be (if you have the modules)
 
Keyboard CV - VCO - VCA audio in - VCA audio out - amp
Keyboard gate - Env - VCA CV in (turn the VCA initial gain to zero)
 
Set env to zero attack and medium decay and you should get a sound when
you press a key.
 
It's the same patch if you replace keyboard with a sequencer.
 
Then you can add a filter between VCO and VCA to colour your patch and
then route the env out to the filter CV as well so it tracks the
keyboard. Add modulation to filter, VCA etc for more interest.

The public way is a A-185 bus access http://www.doepfer.de/a185.htm

The semi public way is taking a A180 multiples 
http://www.doepfer.de/a180.htm
cut the connecting lines between sockets 1, 2, and 3 and solder the 
tip-connectors of socket 1 and 2 to the busboard cvline and gateline.

the semiprofessional diy way is
get a A-100B4 4HP front panel (http://www.doepfer.de/a100z_e.htm) and 
two 3.5mm sockets, drill two holes into the panel, solder wires from the 
  panel to the busboard.

the dirtyhack diy way is
get two 3.5mm sockets, drill two holes into the backpanel (but keepaway 
from the powersupply), solder wires from the jacks to the busboard.


BE AWARE: do not feed additional external CV and gate if you are using a 
MIDI-interface-module like the A190 and if the CV outs of this module 
are already connected to the bussboard.
