Extracting notes and timings of a sample as precise pattern data

I often have a sample or automated sequence in vst instrument that I’d like to extract as precise Renoise pattern data. Getting note pitch right manually is easier, but when it comes to timings and volume I find it really hard. Obvious struggle is with short notes because Renoise doesn’t support ending notes before second line. Luckily you can make phrases with double tempo.

What is your workflow for this kind of situation?

Do you want something like;

it autoslices a sample based on the transients within and auto places the corresponding note events in the pattern with delay values.

Awesome, thanks!
