Thanks for reply!
I’ve tried the slice method on drums and it was OK, but time warp did a better job. Maybe I just used it wrong - I am still a beginner in Cubase.
Wouldn’t that sound bad to have a tiny silent parts in rythm guitar? But I will definitely try that.
The thing is I mainly work with cubase 5, because I have only the lite version of cubase 7. Is it true that the older Cubase doesn’t have a group editing?
