Reaper 2.54 See this project: glueing.rar (130.4 kB) -> load it: You see the first track has two non-looped items with a transient right at the beginning of them. The second track shows the same items glued. -> now zoom in to the end of the glued item => item doesn't end exactly at the loop-marker. you see a spike of the first transient at the end of the item: glueing.png This shouldn't happen. Please either make the item end correctly at the loop-marker or let "loop source" disabled for the glued item! Thanks!
