I'm completely new into modular synths ... until I bought a new 
prebuild A-100 BS2 (thus with the A-190 midi module) a few days ago :-
)
Although it took some time to find my way around, I have been able to 
construct some own patches with decent results.

But now I wanted to use the A-160 in combination with the A-161 for 
the first time.
For one reason or the other, I seem not to be able to get anything 
out of these two modules.
So I'm starting to think that the A-160 module is broken or wrongly 
connected inside the enclosure.

When I plug in a LFO (square) into the trig-input of the A-160, are 
the LEDS of that unit not supposed to start blinking at several 
different rates, depending on the clock division ?
In my case nothing blinks, although the LFO is doing it's job 
(checked that by plugging that LFO into the gate input of an ADSR).
When I connect one of the sub-divisions, for example /4 into the gate 
of an ADSR, that gate is not triggered, so obviously nothing is 
coming out of that /4 output (led also not blinking).
Is also the A-161 not supposed to start "running" through the 8 steps 
(so leds blinking in sequence) when the A-160 is triggered ?
I also tried plugging the A-118 random out into the trig of the A-160 
and also the gate-out of the A-190 midi module.
Nothing seems to be able to trigger that A-160.

By the way, is it possible to try out the A-161 without the A-160 ?
As far as I understand, this is not possible since it needs it's 
clock input from the A-160 ?

Since I have nothing to compare with, I'm not sure what I should 
expect. Maybe I'm doing something completely wrong, but after reading 
the modules manual several times I have the impression that there is 
definitely something wrong with that A-160 module.

Can someone give me some advise on this ?
