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
