It would be much easier to modify the A-182 by adding a diode between each
socket and switch. Simply interrupt the pcb track between socket and switch,
solder a diode between socket and switch (the schematics is shown on the
A-186 page) and add an output socket. That way you obtain a "switched" A-186
gate/trigger combiner.

It would probably take only a few hours to "condense" the A-182 pcb and
front panel to obtain such a module (with 9 sockets and 8 switches). But I'm
not sure if there are sufficient inquiries for such a module. An additional
option would be select between "DC coupled combination" (i.e. gate remains a
steady gate signal at the sum) or "AC coupled combination" (i.e. only the
rising edges of the inputs signals are used to generate the combined trigger
signal). The two types could be distinguished by left/right positions of the
switches (center = off).

This is proving to be a really interesting thread

I think the modules A-160/161 have the disadvantage, that they don't 
start with step 1, but with step 2 (and 160 also does not count 
musically - should be a down counter). So I would not invest into those. 
I think a new generation of PIC based counters and dividers would be 
great. Perhaps even a module group that also would be able to provide / 
read an internal adress bus, so one might combine it with the A-154.

In principle it would be easy for us to combine any of the module A-160/161,
A-182, A-186 and so on to a new combo-module. But in the end it's important
for us if there are sufficient inquiries for such a new module (and which
version). As I'm very busy because of the upcoming Musikmesse in Frankfurt
let's move this discussion after the Musikmesse (at least my contribution).
