Drum Fills in Renoise

*btw you could extract the audio from the youtube clip, cut out the particular break fill and sync it to your projects bpm, use Renoises auto slice function & Dblue’s slices to pattern tool (https://forum.renoise.com/t/new-tool-2-7-2-8-slices-to-pattern/31593) so it will automatically place the slices on the corresponding pattern lines / delay values.

This would give you a quick overview of where to place your own samples, might make it easier to emulate?
