Step repeat only triggering first time through pattern

I’ve had this DrumBrute for a few years now and only noticed this behavior recently.

Basically, if I set a step repeat “ratchet” for any steps and any sounds, the repeat is only triggering properly the first time through the pattern. After that I only get the one regular hit.

(Actually after messing around with the tempo, it seems like the additional hits are still there, just being played really fast after the main hit.)

If I tap the roller strip at any point while the pattern is playing, the step repeat will trigger again the next time through the pattern, but only the first time. This only works to correct the playback if the Shift+9 “Roller” setting is OFF.

I’ve tried doing a full factory reset and reloading my patterns. Didn’t change anything.
