In the manual I didn´t found anything about turning loop mode off (perhaps I overlooked something). I am coming slowly to the point where I want to take the whole machine and want to throw it out of the window. I tried and tried and sometimes it worked (no loop marker anymore, no boxes, and the arrow turns white) but some patterns simply don´t let me and bit by bit I am getting a bit angry over here. loop step channels removes the boxes but puts again an active loop marker in my case at bar 9 in the PR editor and the loop arrow in the title bar stays green even if there is nothing to loop. Turning the loop mode from advanced to i.e. Learn How To Sample in 13 Mins Tutorial for FL Studio Understanding how to sample can be a tricky thing, no matter if you use FL Studio, Ableton, Logic. I set the corresponding instrument to "Don´t loop", I deleted the loop marker in the PR editor but there is no way to get rid of the boxes on the right hand side. Now I want to get rid of that and want to get rid of the loop point boxes which appear in the channel rack after turning advanced loop mode on. I used always advanced loop mode for that.
As for me Loop mode is buggy I try to replace the looped patterns in an existing song by just duplicating the midi data to make the clip the same length like I had before with looping turned on.
