Renoise workflow is non-existent in regards to this AFAIK. The only thing that comes to mind is to pad the sample with silence, and align the beat visually to the guide above the waveform.
(Tools could be made that partially helps, but it didn’t happen yet. For example a tool that moves the note and inserts correct delay value to make the first slice marker align with the cursor position)
PS. I requested a feature in this thread, that would take care of the problem: https://forum.renoise.com/t/note-align-sample-hit-point/32368 . I can’t really see this happening though, since Renoise seems to have gone in a different direction since I posted this.
