thank You for the answers, indeed I need the grid for arranging, for mixing I wouldn't bother just leave it 120 bpm
. So I'll try matching to grid, I need to check how to do this properly. The reason for my question was that I also tried the stems in ableton and it worked well. Ableton put the stems into 4 bar clips at once. I think this is due to its warping function. Anyway I've been working in Reaper for more than a year, know this DAW really well, so I'd rather work in Reaper than Ableton( lite version that I own has only 8 audio tracks
)
