Slicing is a lot more time consuming and harder to do when the loop is more complex… in fact… i spent an hour today just trying to get one drum loop to sound good sliced (even without stretch), and i couldn’t get it anywhere near as good as logic/pro tools/ableton/S1 auto slicing to tempo feature…
so for altering the speed of drums to project tempo, i maintain cubase is very far behind. It’s a shame, i hope they change it and add a properly tuned rhythm algorithm.
