hello bryan,

from my experience you need the a185 only when sending a
pitch cv to multiple origins, lets say you send a quantized
voltage to three vco's and a filter. as long as you use a
buffered multiple like the a185 you will be fine, but when
using an unbuffered multiple like a180 the cv voltage will
drop at a certain point and maybe your vco's will be out
of tune then.
the a185 feeds the system buss of the a100, so if you want
to use the system buss, you need the a185.

to shortly answer your question, you do not necessarily need
an a185, but sometimes it makes life a lot easier
if you have one.

hope this helps

best wishes

ingo

Access module. I'm not clear on what it does. If I send my Doepfer
lfo to a bunch of different sources, will the signal somehow
degrade I have a Doepfer suitcase system and I'm always sending the
cv's to a multiple and then off to other places in the Doepfer system
and to my other racks of Blacet/Wiard modules. I haven't noticed
that this is a problem, but I'm not always very scientific about
analyzing my patches.
