I am considering A-154 Sequencer controller plus two A-155 sequencers 
combo. I have already one A-155 along with A-154 (and one A-150 VC 
Switch). After reading the manuals I have some doubts. Please, read 
on.

1 to 8 step sequences:
This seems pretty straightforward. 

9 to 16 step sequences:
CV1 Pre Out, CV2 Pre Out, Trig1, Trig2, Trig3 and Gate outputs from 
both A-155:s must be switched. Threfore six voltage controlled 
switches are needed, which translates to three A-150:s. If CV1 Post 
Out and CV2 Post Out are added, then one more A-150 is needed... This 
seems like lots of modules and cabling for a simple task (but on the 
other hand those A-150:s can be used for something else too). Another 
drawback I can see is, that when moving from step 8 to step 9 
(changing from one A-155 to another), there can be no glide or S/H 
control.

Two independent sequences:
Assuming the modules are connected normally the A-154 controls both A-
155:s or neither depending on the "Man." switch position. However, it 
would be useful to have a third option: A-154 controls one A-155 
while the other A-155 is independent. I wonder, if there is an easy 
solution for this.   

Here is the total cost:
- 1 X A-154: Euro 170
- 2 X A-155: Euro 520
- 3 X A-150: Euro 150
- 1 X A-180 (Bridged, distributing the 1-8/9-16 signal from A-154 to 
the A-150:s): Euro 30
Total: Euro 870

I have seen A-154 + A-155 + A-155 combo in few pictures, so 
apparently it is useful. I would like to hear your comments.
