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

2014-11-28 by achtung_999

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

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 :-)
