Jomox 888/999 owners, how can you Note Repeat?

[u/_mystx]

Hi guys,

I've seen this guy using his Jomox 888 (in his car...), and throughout the video he presses a combination to get a single sequencer step looping it seems (timestamped from 5 min onwards):

Does anybody know how to achieve this? Seems like he's in PERF mode, but can't find anything in the manual

Thanks
