This was tapped by @shigginpit as the cause of an issue that manifests as “time between triggers is never consistent” even though it does not logically make sense.
I went and tested anyway. Both using “start” and using “threshold” as the trigger at 120 produce perfect length files as confirmed by loading into ableton and turning warp off. So this never was the cause of the issue, because it has already been fixed in a firmware update. (and incorrect timing for the total length would not cause timing inconsistencies between triggers to begin with.)
For more information on the “delta time between triggers is never consistent” see the following thread, it could save you some major problem solving headaches in future:
Note this is present on the DT/DN/DT2/DN2 they are all running the same processor. I doubt that will be fixed in an update.
