Whenever you drive more than 2 VCOs from the same CV source (e.g. A-190,
sequencer, keyboard ...) a bus access module (A-185-1 or A-185-2) is
recommended. The advantage of the A-185-2 is that you can add several CVs
that affect all VCOs (e.g. sequencer to CV2 + keyboard to CV3 + modulation
with attenuation to CV1).
