A154 First/Last Steps with 2xA155s in series

2014-11-28 by sj230962@gmail.com

Hi all - did a quick search through the old topics but couldn't find an answer to my question, so here goes...

How does the First/Last step controller work when 2x155s are in series, linked by the A150 VCS ?

When the 9/16 switch is flipped, does the last step output automatically have 8 added to it so it addresses steps 9-16 on the second A155 ?

Example, I want to run random seq/pendulum etc between steps 3-13 : can I do this ?

Reason for asking is that my 2nd A155 is in the post today and I wanted to think about this issue before it arrives.

Appreciate any advice

Steve

I only have one and I'm still too comfortable under the covers to go an check, but couldn't you test this with just one?  Flip to 9/16 and adjust last step.  If it shortens the pattern, then I suppose it does not work as you hoped.  In that case, consider an MAQ16/3, but then such changes to the sequence cannot be made with CV (unless you have CVtoMIDI)

Thanks for this Nick.  I’ll go and do that right now!  Funny how the simple things evade me.

As for the 16/3..I have one.  And a Schaltwerk.  But looking to sell both in the coming weeks - just simply run out of room living abroad here in Malaysia. Small apartment and lots of gear (plus wife) doesn’t always compute :-)

Yes, this will work - provided that the A-154/A-155/A-150 are patched correctly. But for both A-155 the steps 1-8 will be addressed
in parallel. The switching between the stages 1-8 and 9-16 is carried out by the A-150 which is controlled by the 9-16/A3 output of
the A-154.

2014-11-28 by Steve Jenkins

Thanks Diieter - but I’m still a little confused.

If the 2xA155s are running in parallel and I select  first at step 2 and last at step 5 (on the dials - but what I really want to select are step 2 and step13 of a 16 step sequence), then when the first A155 cycles through, the A154 will address steps 2 and 5, and simply cycle between them and step 8 is never reached to trigger steps 9-16.  Even when the first A155 has 8 steps the  A150 switches to the CV output of the second A155, won’t the fist and last steps still be 2 and 5 be addressed again at the same place on the 2nd unit and stuck in that cycle from steps 10-13?

Sorry for making this sound complicated - I’m sure there is a simple explanation that eludes me :-)

Just patch this as you read along.....

A155 #1: top row > A150 (top) input 1, bottom row > A150 (top) input 2, vc input A150 (top) via mult from 1-8/9-16 output A154. Output A150 (top) = first 16 step sequence

A155 #2: top row > A150 (bottom) input 1, bottom row > A150 (bottom) input 2, vc input A150 (bottom) via mult from 1-8/9-16 output A154. Output A150 (bottom) = second 16 step sequence

As already mentioned the A-150 does the switching between steps 1-8 (A-155#1) and 9-16 (A-155#2). When the A-155 is not selected by
the A-150 it does not matter which step is adressed. If you select e.g. 5/11 as first/last step both A-155 will be addressed that
way: 5-6-7-8/1-2-3/5-6-7-8/1-2-3 and so on. The A-150 does the switching between the steps 5-6-7-8 coming from A-155#1 (which are
the "real" steps 5-8) and 1-2-3 coming from A-155#2 (which become the "virtual" steps 9-11).

I hope this helps to understand the A-154/A-155 combo. Please refer also to the A-154 user's manual (especially the pages 9-11)

Re: [Doepfer_a100] A154 First/Last Steps with 2xA155s in series

2014-11-28 by Steve Jenkins

Thanks Heinrich - I have read the A154 manual and understand the switching between the modules. The thing I couldn’t quite get my head around is how the sequence could progress to step 8, thereby triggering the high voltage to get the A150 to switch routing to A155#2 if the first and last steps are 2 and 5 , which in my head says the sequence cycles between 2 and 5 on A155#1 and doesn’t progress forward to trigger then A150 to move to A155#2.

Anyway - a few glasses of red wine on a Friday evening doesn’t help the thought process…but when my 2nd 155 arrives I’m sure everything will be fine :-)
