I’ve been trying to figure out on the Octatrack how to set the change length ?
It only has a master length. It doesn’t change in time after 64 steps with the A4 and Rytm when I want make longer patterns than 64 because I have to set the master higher on the OT To 128 to play the whole pattern…
I set the chain after to 64/16 in control >sequencer …but it still changes late
It´s in the Pattern Settings menu [Function] + [Bank] when not in Grid Recording Mode, “Use PAT SET” let´s you specify for how long a cued pattern plays before changing.
Thanks that worked! I was changing it in control >sequencer
The setting under Control -> Sequencer -> “Chain After” affects all patterns in all banks across the whole the project.
Basically a global setting for the project.
If you want to use this setting, enable “Use Proj Set” in Pattern Settings menu (It´s right under “Use Pat Set” in Pattern Settings and patterns will change accordingly to the settings you specified in Project Menu.
More flexible not to use the global settings ofc, Pattern Settings Menu let´s you set individual change length for each pattern 
Yep just figured that out I understand now, thanks man!
