Had already tried option 2 - didn’t seem to work (see original post)
Option 3 has helped at lot - I think this seems to be the essence of trackers/Renoise in this regard. If you want finer control over rhythm, mess about with bpm/speed.
However, I still can’t seem to record a syncopated/ off the beat hihat pattern “live” from my Midi keyboard - obviously if I set the Editstep to 1, no matter what rhythm I tap out, each note goes on a consecutive line.
There is obviously something I’m not doing right here - or this is way it is with trackers … ?
