When I play specific patterns on the OT mkI (1.25h) with this speed (really long samples) I set the master length to 512 (64 steps times 8) and then when I chain the next pattern both A4 and AR changes pattern only after they’ve gone through a cycle. On all my other patterns in the same bank everything runs as expected. Anyone else experience this?
To me this seems like the OT can’t handle proper pattern changes when in this extreme setting? Thankful for any insight in this, cheers! 
I have this issue otherwise, when the chain is like this: AR > A4 > OT
The OT is always one pattern behind
Yeah I had a similar issue, but that was because I connected via AR midi OUT instead of thru. Which makes the devices following in the chain be one pattern behind (the AR sends the pattern switch when it’s already done the switch, from what I’ve gathered). But now, the connection is OT>AR>A4 with the midi thru used on AR. As I said this only happens with patterns that are really long and on the slowest scale!
