Thanks for your help. Exactly that was my problem :D
Thanks for you answer. I checked if i did so but unlikely it did not help. I open a beat/bassline in the piano-roll but i still was not able to stretch the segment. This is the case for all elemts which are compatibil with the piano-roll.
Hello,

i have used lmms for a week or so now. Since two days i have the problem of not being able to stretch passages in the piano roll. I do not know why but the notes turned green somehow.

Could need some help :D
